One-piece swimsuits for women by SwimZip

Our one-piece bathing suits for ladies

Our high-quality, durable swimsuits transform your time in the water with thoughtful features that enhance comfort and functionality. Our flattering seams create a slimming silhouette while accommodating different body shapes with a true-to-size fit.

For active water sports such as kayaking or surfing, convenient thumb holes prevent sleeves from riding up and provide constant UV protection. The back zipper's long pull cord lets you slip in and out without struggling or awkward reaching.

Enjoy supportive features including removable modesty cups to customize your coverage level and a full lining that maintains opacity whether you're wet or dry. Thoughtful design elements such as strategic seaming contour your curves while providing complete coverage and unrestricted movement.

Turn heads in our stylish patterns while enjoying a secure fit that stays in place through every activity, from swimming laps to chasing kids around the pool.

Sizing and fit

Our size selection spans from infants through teens, so your child will find the right fit for all water adventures. Check the size chart for specific bust, waist, and hip measurements so you can determine the perfect size and find clear instructions about the measuring process.

Our swimwear fabrics

SwimZip selects premium fabrics for active performance. Each piece delivers proven function with exceptional fit.

Our lightweight, quick-drying materials prevent water saturation and maintain comfort in and out of water. The fabric pulls moisture away from your skin and resists breakdown from chlorine, salt, and sun exposure.

Each suit includes UPF 50+ protection that blocks 98% of UV rays. Our fabrics shield against premature aging and reduce skin cancer risk during outdoor activities.

The four-way stretch creates a secure, flexible fit. This means you can swim, surf, or lounge without constant adjustments.

For cold water, our breathable fabrics retain warmth. The durable construction prevents tears and snags, extending your swimwear's life through multiple seasons.

Why is sun protection important?

Our skin absorbs UV radiation from direct sunlight every time we step outside. Over time, this exposure leads to wrinkles, dark spots, sun poisoning, and an increased risk of skin cancer.

During water activities, your skin needs extra defense. Acute sun damage creates painful burns, blisters, and potential sun poisoning. Children face even higher risks since their skin is more sensitive to UV rays.

The sun emits two types of UV rays that reach Earth's surface. UVA rays penetrate deep into skin layers, while UVB rays cause sunburns and skin damage. Both contribute to skin cancer risk.

Proper protection, including extra coverage options, blocks these harmful rays. UPF 50+ fabrics stop 98% of UV radiation, along with sunscreen for complete coverage.

What other swimwear do you offer for women?

In addition to one-piece bathing suits, in our swimwear collection for women, you will also find:

Rash guards: These tops provide excellent coverage, shield your skin from harmful UV rays, and offer a stylish and comfortable fit for water activities. You can choose between short and long-sleeve rash guard designs.

How to style one-piece swimwear

Our one-piece swimsuits adapt to countless occasions. Here's how to create polished looks with your favorite piece.

A flowing wrap skirt tied at the waist creates an instant outfit for walking to lunch or browsing shops. The simple design brings elegance to any swimsuit.
A crisp button-down shirt becomes the perfect cover-up for casual restaurants. Leave it open over your suit or tie it at the waist for a polished look.
The right accessories transform your pool look. A wide-brim hat and woven beach bag protect and polish your style.
Different textures add visual interest to your outfit. Try a crochet kimono that keeps you cool while looking sophisticated.
Your swimsuit forms the foundation for a complete outfit. High-waisted linen pants complement your natural shape perfectly for sunset dinner.
Choose shoes that suit your activities. Sturdy sandals support water aerobics, while dressy options work for evening events.
For upscale beach clubs, wear a tailored wrap swim dress over your suit. You'll look elegant while staying ready for a spontaneous swim.
Long, flowing skirts or palazzo pants balance the fitted silhouette of a one-piece, creating outfits that work for any occasion.

One-pieces are among the most versatile swimsuit styles that offer moderate coverage while maintaining elegance. They're perfect for active water sports, provide excellent sun protection, and create a stylish silhouette for many body types.
