Let’s explore how to select a bikini that belongs in your beach bag.
Understand your body shape
Your body shape determines which bikini styles will flatter you best. Each bikini cut highlights specific body features. A well-chosen bikini top emphasizes your assets while bikini bottoms balance your proportions. Here’s a rundown on body types:
- Triangle body shape: Your shoulders appear proportionally narrower than your hips. The most flattering bikini styles are bandeau tops with ruffles or details that add width to your shoulders. Push-up underwire tops with patterns attract attention upward, which creates visual balance. A solid dark bottom paired with a decorated top will complement your natural proportions.
- Pear body shape: Your hips, thighs, and buttocks are your best features. Side-tie bottoms offer adjustable coverage that fits your curves. A high cut elongates your legs, and dark-colored bottoms proportion the lower body. Tops with patterns, ruffles, or embellishments pull focus upward to balance your silhouette.
- Inverted triangle body shape: Your broad shoulders and bust taper to narrower hips. High-waisted bottoms create an hourglass silhouette, and skirted or ruched bottoms add feminine curves. Simple, solid-colored tops minimize your bust, and wide-band bottoms balance your proportions.
- Hourglass body shape: Your proportional shoulders and hips frame a well-defined waist. Underwire tops give you needed support, and halter styles showcase your shoulders. Mid-rise bottoms follow your natural curves, and matching sets highlight your balanced proportions. Triangle bikini tops let you adjust coverage for comfort.
- Rectangle body type: Your shoulders, waist, and hips share similar widths. Padded push-up tops add dimension, and ruffles on tops or bottoms create soft curves. Brazilian cut bottoms shape your silhouette, and twisted bandeau bikini tops add visual interest. Color block designs highlight natural curves.
- Apple body type: Your fuller middle section stands out from your shoulders and hips. Halter tops deliver built-in support, and tankini tops gracefully slim your shape. High-waisted bikini bottoms smooth your silhouette, and solid dark bottoms complement patterned tops. Wide-band tops slim the ribs.
Once you’ve figured out your body shape, you can think about coverage and support requirements as well as your planned activity level.
Think about coverage and support
Your bikini should look good, but it also needs to stay where you put it. Bikini top support starts with understanding your cup size. A to C cups can wear most styles, but D cups and above need stronger support. A properly supported bust sits midway between your shoulders and elbows, with the fullest part of your breast centered in the cup.
Bikini top fit tips
Here are the signs a bikini top fits you right:
- No breast tissue spills from the sides or top.
- The band stays parallel to the ground without riding up.
- Straps rest flat without digging into shoulders.
- The underwire lies against the ribcage without floating.
- The center panel touches your sternum.
Support features to look for
Underwires
Underwire styles lift and separate your bust and anchor the top in place, preventing forward movement during activities. When paired with wide, comfortable straps, the weight distributes evenly across your shoulders without digging in or creating sore spots.
Tie straps
The adjustable tie straps create a custom band fit without gaps. You decide the amount of support and compression for maximum comfort.
Cup adjusters
Repositionable cups give you control of your coverage. The sliders adjust cup placement to match your preferences and create your preferred silhouette.
Hook closures
Multi-position hook closures deliver exact band sizing for a secure fit. These flat closures offer a smooth back appearance plus the ability to adjust tightness throughout the day.
Wide waistbands
A broad, reinforced waistband stays in place during movement without rolling or digging. The extra fabric provides gentle tummy control for a smooth silhouette.
Double-layer fabric
Two layers of premium fabric offer full coverage that remains opaque in water. The double construction smooths your curves and prevents the bottoms from clinging.
Ruched panels
Strategic ruching on the sides and back creates visual interest and texture. The gathered fabric contours to your shape for a flattering, secure fit.
Bikini coverage
Tops
Full coverage tops provide the security needed for larger busts, sports, and other high-energy beach activities by keeping things in place through waves and movement.
Those seeking moderate coverage for standard beach activities such as swimming or beach walks will find comfortable support in standard cuts that balance security with freedom of movement.
Smaller busts benefit from lighter coverage options during relaxed activities, though all coverage levels benefit from UV-protective fabric that adds an essential layer of sun safety to your beach experience.
Bottoms
Full coverage bottoms extend from hip to hip in front and provide complete seat coverage in the back. This style offers maximum security during active water sports and eliminates the need for adjustments.
Moderate coverage bottoms show more leg with a medium-cut leg opening and partial back coverage. These styles stay put during regular beach activities without restricting movement.
Minimal coverage bottoms feature high-cut leg openings and less back coverage. These styles suit sunbathing and light beach activities when you want to minimize tan lines.
Explore bikini styles
Bikinis flatter different body types, support many activities, and provide customized coverage with sun protection. The right top and bottom will become your favorite beach companion.
Bikini top styles
From minimal to full coverage, bikini top styles suit different support needs and comfort levels:
- Triangle tops include adjustable fabric triangles that connect to a band under your bust. You can slide these triangles along the band for custom coverage and support, plus adjust the shoulder straps that tie at your neck and back. This classic style provides lightweight support for A–C cups.
- Bandeau tops use a single band of fabric that wraps around your chest with built-in silicone grip tape to prevent slipping. Removable straps add versatility when you want extra support. This style suits smaller busts best and creates minimal tan lines during gentle beach activities.
- Sports tops feature a crop-style design with sturdy wider straps and a higher neckline. The strong elastic band grips your ribcage securely, and many styles include molded cups or light padding. This athletic design stays firmly in place through volleyball, surfing, and active swimming.
- Underwire tops use structured cups with wire support to lift and separate your bust. The strong band anchors against your ribs while adjustable straps distribute weight. This essential style gives D+ cups proper support during any beach activity.
- Halter tops feature straps that tie behind your neck for adjustable lift and support. The full cups provide excellent coverage that suits all bust sizes, and you can customize the pressure by adjusting the necktie.
- One-shoulder tops combine athletic support with an asymmetrical design. The single thick strap provides stability across your shoulder and back, while the straight-cut neckline adds modern appeal. This style balances fashion with function for smaller to medium busts.
- Scoop neck tops follow your natural neckline curve with a rounded cut that flatters your collarbones. The classic U-shape design provides full bust coverage without feeling restrictive. A stretchy band under your chest adds support without uncomfortable compression.
- Front tie bikini tops include an adjustable knot or bow between the cups. This center detail creates subtle ruching that enhances your natural shape. The ties let you modify the space between cups for a perfect fit, while standard back closures keep everything secure.
Bikini bottom styles
Bikini bottom styles vary in coverage and rise to flatter every body type:
- Full briefs provide complete bottom coverage with higher leg holes that elongate your thighs. The secure fit excels during swimming and active water sports, as the fabric stays firmly in place through every movement.
- Moderate-cut bottoms show more leg while maintaining reliable rear coverage. Your natural waistline provides the perfect resting spot for the mid-rise design to create a balanced look that suits all beach activities.
- Cheeky bottoms reveal more skin through strategic coverage placement. The higher leg holes create long lines that flatter your natural curves. This style is perfect for sunbathing and casual swimming.
- Brazilian bikini bottoms combine minimal rear coverage with a mid-rise front. This design naturally elongates your legs and emphasizes your curves. Women love Brazilian cut bikinis for sunbathing and gentle water activities.
- High-waisted bottoms rise above your belly button with full rear coverage. The smooth front panel contours your shape, and different leg cuts let you personalize your coverage level.
- Side-tie bottoms feature adjustable strings at your hips. The ties modify tightness and coverage to adapt to your body shape and comfort preferences.
Activity level and purpose
The activities you love affect which bikinis work best for you. During volleyball, you need a swimsuit that stays in place, while during a casual tanning session, you want maximum exposure and minimal lines.
Surfing, swimming laps, and beach sports require secure bikinis that won't shift or move. Look for thick elastic bands, supportive straps, and full-coverage bottoms. Cross-back designs prevent slipping during active movement. The fabric blocks UV rays through hours of outdoor play. You can throw a rash guard over the top for extra protection and support.
Beach walks and casual swims pair well with adjustable bikinis that adapt to your preferences. Side-tie bottoms and tops give you control over coverage and fit. The fabric stands up to water and sun, maintaining coverage when wet while blocking UV exposure.
Water parks demand maximum security. One-piece styles and tankinis prevent wardrobe mishaps on slides or in waves. High necklines and full bottoms keep everything exactly where it belongs. Sturdy clasps and ties won't come undone during active play. UPF protection matters most during peak afternoon hours at outdoor parks.
Beach lounging lets you focus on style and sun. Bandeau tops create clean tan lines, while adjustable strings give you the perfect fit. Brazilian cut bottoms maximize your tan. Light support works for smaller busts during relaxed activities. The UPF fabric protects your skin through long days of sunbathing.
Fabric considerations
A bikini needs a fabric that stands up to sun, salt, chlorine, and daily wear. Strong materials keep their shape and color while blocking UV rays for long-lasting skin protection.
Signs of quality fabric
The best bikini fabrics tell you their quality at first touch. Quality fabrics bounce back after stretching. Thick, smooth material resists snags and won't become see-through in water. Clean, even stitching and lined show careful construction that will last you multiple seasons. Look for:
- Double-layered fabric in important areas.
- Flat, secure seams that don't rub.
- Strong elastic that keeps its stretch.
- Consistent color with no fading.
- Material that dries quickly.
See our guide on swimwear fabrics.
UV protection and sun safety
UPF 50+ fabrics block 98% of UV rays from reaching your skin. A UPF rating measures how much UV radiation passes through the fabric. UPF 50+ stops UVA rays that age skin and UVB rays that cause sunburn. This protection works even when the fabric gets wet or stretches during beach activities.
The color and construction of swim fabric affect its UV-blocking power. Darker colors absorb more UV radiation before it hits your skin, while bright neon colors reflect UV rays away from your body. Tight fabric weaves create a denser barrier against sun damage, while loose knits let more UV light pass through gaps between threads.

Swim performance
Pool chemicals break down standard fabrics, but chlorine-resistant materials maintain their stretch and color. Saltwater also damages low-quality fabrics after constant exposure. Quality nylon-spandex and polyester blends stretch effectively, resist chlorine, and dry quickly. Cotton soaks up water and loses its shape when wet, so it’s not a great swimwear fabric.
SwimZip uses UPF 50+ rated fabrics in every swimwear piece. These fabrics maintain their sun-protective properties through hundreds of wears and washes. The tight-knit construction blocks 98% of harmful UV rays while staying soft and breathable against your skin.
Our signature fabrics include:
- Full lining for maximum coverage.
- Quick-dry technology that pulls moisture away from the skin.
- Chlorine-resistant fibers that keep their shape and color.
- Four-way stretch that moves with your body.
- Fade-resistant dyes that stay bright season after season.

Choose the right colors and patterns
The right colors and patterns flatter your skin tone and match your style. Your swimwear color choices affect appearance and safety in the water.
Colors for your skin tone
(Image source: https://whysogorgeous.com/blog/determine-your-skin-tone-with-skin-tone-chart/)
Cool skin tones glow in jewel colors: sapphire blue, emerald green, and deep purple bring out natural undertones. Ruby red and royal blue create a striking contrast. Silver metallic accents add sparkle that complements cool complexions.
Warm skin tones radiate in earth tones and tropical bright colors. Coral, turquoise, and golden yellow enhance natural warmth. Orange and lime green pop against warm undertones. Gold metallic details add a rich dimension.
Olive skin tones shine in warm and cool colors. Deep red, bright white, and electric blue create a beautiful contrast. Pastels such as mint green and soft pink offer subtle enhancement.
Water safety colors
Neon colors stand out in water so swimmers become easy to spot. Bright yellow, orange, and hot pink catch attention through waves and splashes. These high-visibility options are best if you plan to swim far from shore.
Pattern play
Patterns affect the perception of your body shape and skin tone and add another dimension to bikini styling. Here are some things you should know about patterns:
- Small, repeating patterns elongate your figure.
- Large prints draw attention to specific areas.
- Vertical stripes create length while horizontal stripes add width.
- Tiny florals work for most body types.
- Bold geometrics make a statement.
- Vertical stripes lengthen the torso and legs.
- Color blocks shape your silhouette and show your best parts.
- Animal prints add visual texture.
Mixing separate pieces
Top and bottom colors should create a cohesive look. Match one color between pieces when mixing patterns. Keep one piece solid when the other has a busy print. Similar color families blend together.
SwimZip’s neon swimwear comes in safety-conscious colors that stand out in the water. Our prints range from classic stripes to playful patterns, with mix-and-match options for the whole family. Every piece in our sun-protective swimwear collection uses colors that maintain visibility while blocking UV rays.
Get the perfect fit
A bikini that fits your body stays comfortable through every beach activity. Accurate measurements guide you to the right size from the start.
How to take measurements
Your hip, waist, and bust measurements will unlock your perfect size. Wrap a soft measuring tape around your fullest bust point without compressing. Measure your natural waist at the narrowest point. Take your hip measurement at the widest part of your hips and bottom.
Check out SwimZip’s size chart with detailed measurements for each size, including bust, waist, and hip measurements. We also offer a helpful guide on how to measure the body to determine the best size for your new bikini.
Common fit problems
Bikini tops often reveal fit issues through cup gaps or overflow. When cups gap away from your chest, try a smaller size or different style that matches your bust shape. Overflow at the cup edges means you need more coverage from a larger size or fuller cup style.
A band that rides up or straps that dig into your shoulders point to incorrect sizing that proper measurements can solve.
Adjustment features
Many bikini styles include built-in adjustment points that perfect your fit. Adjustable straps let you customize the shoulder comfort and cup position. Back ties or clasps modify the band tightness for secure support. Side ties on bottoms adapt to your hip shape while sliding cups control your coverage level.
Tips for trying on bikinis
Armed with your new bikini knowledge, you’re ready to go shopping. As you hunt for the right bikini, use these tips to help confirm the fit and match.
- Move in the bikini: sit, bend, stretch, squat, and reach up. The suit should stay securely in place.
- Bring several sizes of the same style to compare.
- Wear a nude-colored sticky bra if you want to test padding removal.
- Stand straight and relaxed; no poses or sucking in.
- Look at your side profile in good lighting.
- Test removable straps on and off.
- Pull gently on the seams to check the stitching quality.
- Check that printed patterns align at the seams.
- Move around in the suit for at least 5 minutes.
- Test that clasps and ties stay secure during movement.
- Look for see-through spots in bright light.
Useful shopping tips
Find your perfect bikini at specialty swim retailers, such as SwimZip, Lands' End, and Venus, where product experts can guide your selection. Large retailers, such as Target and Old Navy, offer budget-friendly options but may lack specialized features. Department stores including Nordstrom and Macy's carry popular brands such as Tommy Bahama and La Blanca.
When trying on bikinis, bring basic items that make the experience smoother. A hair tie keeps your neck visible, while flip flops let you inspect the whole ensemble. Your current favorite swimwear can help you compare fits and features. Most stores allow fit photos that let you review styles later.
How to care for and maintain your bikini
Proper care extends your bikini's life and maintains its protective features.
- Rinse your bikini in cool water right after swimming to remove chlorine, salt, and sunscreen.
- Hand wash in mild soap, then roll the bikini in a clean towel to absorb excess water.
- Avoid wringing or twisting the fabric, which stretches out elastic and damages seams.
- Let your bikini dry away from direct sunlight, which fades colors and weakens the fabric.
- Lay the bikini flat to prevent stretched straps and misshapen cups.
- Skip the washing machine and dryer; harsh agitation and heat break down elastic and protective coatings.
- Store your bikini flat in a drawer rather than hanging, which pulls on straps and bands.
- Keep the bikini away from rough surfaces that might snag the fabric.
- Between beach trips, store your bikini in a cool, dry place to prevent mildew growth.
Replace your bikini when the fabric shows signs of wear. Stretched elastic, faded colors, or thinning material mean it's time for a new suit. Saggy bottoms or unsupportive tops won't give you the coverage and comfort you need.
