Tie side bikinis for women

What are side tie bikini bottoms?

Side tie bikini bottoms feature adjustable fabric ties at each hip that let you customize the fit and coverage. These tie bikini bottoms sit at a medium rise, typically a few inches below your belly button. The design came from vintage swimwear styles but has evolved into a modern favorite for women who value fashion and function.

The tie mechanism works by threading fabric through small loops or eyelets, similar to shoelaces. You can tie them in bows, knots, or leave them loose for different looks. Unlike regular bikini bottoms, tie side bikini bottoms accommodate body changes throughout daily, monthly, and seasonal weight fluctuations.

About our side tie bikini bottoms

Each pair of our side tie bikini bottoms features reinforced tie points that won't tear or stretch, so your bikini bottoms will last for countless summer seasons.

Our signature construction includes double-stitched seams and premium hardware that withstands saltwater exposure and frequent washing. The ties are cut from the same UPF 50+ fabric as the bottoms for consistent sun protection and color matching.

Our tie side bikini bottoms are built for function and comfort:

Chlorine-resistant fabric that maintains elasticity
Tagless construction prevents irritation
Flat-seam technology reduces chafing during extended wear
Four-way stretch accommodates active movement
Quick-dry technology pulls moisture away from skin

You can fasten these tie swim bottoms to match your mood and beach activities. Tie them high on your hips for a retro pin-up look, or position them low for contemporary beach style.

Pair our side tie bottoms with crop tops from our women's rash guard collection for sporty elegance, or choose a halter bikini top for classic beach glamour.

Our other women's bikini bottoms

In our collection of bikini bottoms for women, you will find:

High-waist bikini bottoms sit above your belly button with retro-inspired styling. They provide extra tummy coverage and create a flattering silhouette that smooths your midsection.
Classic bikini styles feature traditional cuts with moderate coverage. These timeless designs work well for most body types and water activities.

Sizing and fit

Start with our bikini guide and use your hip measurement as the primary guide. Many customers find they can comfortably wear a size up or down from their usual swimwear size due to the tie adjustability. This flexibility makes side tie bottoms great for gift-giving or when you're between sizes.

The ties allow for micro-adjustments throughout wear. Begin with a comfortable tie tension when dry. The fabric will shift slightly when wet, and you can easily retighten if needed. For extended swimming sessions, tie a double knot to prevent loosening from wave action or diving.

Our size range accommodates XS through XXL, with tie lengths proportioned to each size for fit and styling. Petite frames can wrap the ties multiple times for a decorative bow effect, while our plus-size swimwear for women gives fuller figures ample tie length for comfortable positioning and the same stylish options in extended sizes.

Our swimwear fabrics

Every SwimZip garment begins with carefully selected soft materials engineered for performance and longevity. Our tie bikini bottoms use a proprietary blend of nylon and spandex that delivers superior stretch recovery, meaning your bottoms return to their original shape after each wear.

The fabric construction features a tight knit structure that blocks UV radiation without chemical treatments that can wash out over time. This mechanical sun protection maintains its effectiveness throughout the garment's lifespan, unlike coated fabrics that degrade with use. Our commitment to superior sun protection has earned us the Skin Cancer Foundation Seal of Recommendation, recognizing our swimwear's proven ability to help prevent sun damage.

Our luxe fabrics include moisture-wicking fibers that transport perspiration away from your skin, preventing the clammy feeling common with average bikini bottoms. The antimicrobial properties built into the fiber structure resist odor-causing bacteria, keeping your suit fresh between washes.

Color retention technology keeps vibrant options true wash after wash. Our dyes are formulated for swimwear applications, resisting fading from chlorine, saltwater, and UV exposure that typically bleach out other fabrics.

Choose from bold colors, essential colors, and captivating prints that maintain their beauty season after season. For water safety, certain swimsuit colors offer better visibility underwater when selecting your perfect shade.

Why choose sun-protective swimwear?

Swimwear with UPF 50+ provides superior defense against harmful UV rays. Here's why you should choose UPF tie side bikini bottoms:

Prevent sunburn and skin damage: UPF 50+ fabric blocks 98% of burning UVA and UVB rays, protecting your skin during extended sun exposure. This reduces your risk of sunburn, sun poisoning, and long-term skin damage.
Reliable protection: Unlike sunscreen that wears off, UPF protection is built into the fabric. You can swim, play, and be active without worrying about reapplying sunscreen to covered areas.
Comprehensive coverage: UPF swimwear protects areas that sunscreen often misses, such as your lower back and hip area, where tie bikini bottoms provide coverage.
Perfect for sensitive skin: UPF fabrics create a physical barrier that protects those with sun sensitivities or medical conditions.
Peace of mind: With built-in sun protection, you can focus on enjoying beach adventures and family time without constant sunscreen monitoring. Our sun-protective swimwear collection offers comprehensive protection for the whole family.

How to wear tie side bikini bottoms

Getting the perfect fit with your new tie side bikini bottoms is easier than you think. These adjustable swimwear pieces offer flexibility that fitted bikini bottoms can't match.

How to put tie side bikini bottoms on

Step into the bottoms and pull them up to your desired height, typically a few inches below your belly button for the most flattering look.
Start with loose ties to position the bottom portion where you want it to sit.
Pull the ties evenly on both sides to avoid lopsided positioning that can look unflattering.

Securing the fit

Use a double knot or bow for secure wear during swimming and water activities.
Ties should feel snug but never cut into your skin or leave marks.
You should be able to slide one finger comfortably under the tied area for proper fit.
If you see indentations on your skin, loosen the ties. If they slip during movement, tighten them slightly.

Positioning for your body type

High tie placement creates longer-looking legs, great for petite frames.
Lower positioning offers a relaxed, contemporary vibe that flatters most body shapes.
Experiment with different heights throughout the day to find what makes you feel most confident.

Tie side bikini FAQ

Should bikini bottoms be tight or loose?

Tie side bikini bottoms should feel secure without cutting into your skin. When tied securely, they provide day-long comfort while staying in place during beach activities. Signs they're too tight include red marks, difficulty moving, or fabric bunching. Too loose means they shift during movement or feel baggy when dry.

How do I make bikini bottoms stay in place?

The innovative design of tie side bottoms gives you complete control over fit and security. For active swimming, tie secure double knots positioned slightly higher on your hips. For lounging, a standard bow is fine. Create a small loop before your final knot to prevent ties from pulling through. Our UPF 50+ fabric maintains elasticity better than basic bikini bottoms, helping these tie swimsuit bottoms hold their shape and position longer.

Is it OK to share bikini bottoms?

Sharing bikini bottoms isn't recommended for hygiene reasons. Swimwear comes into contact with sensitive areas and can harbor bacteria even after washing. Each person's body chemistry and fit needs are different, making shared swimwear uncomfortable and potentially unhealthy.

What colors work best for tie side bikini bottoms?

For water safety, certain neon orange, yellow, and green offer better underwater visibility. Black bikini bottoms are universally flattering and slimming, while captivating colors and fun prints add personality to your beach look. Try different colors to see what you like and what colors match your skin tone.

Can you wear tie side bikini bottoms for water sports?

Fitted bikini bottoms are more secure for water sports. But if you tie a good knot, tie side designs will stay in place during surfing, volleyball, or swimming. Our swimwear bottoms feature four-way stretch and quick-dry technology, making them the perfect solution for athletic beach activities.
