A great one piece swimsuit is the easiest way to look pulled-together at the pool, on the beach or at a resort day party. The best one piece for you comes down to three things: the neckline, where the suit adds coverage or cutouts, and how it fits through the torso.
Forget the idea that a one piece is the "safe" option. Today's one-piece swimwear can be just as daring as a string bikini, with sculpted cutouts, asymmetric straps, lace-up sides and shimmer fabrics that look amazing in photos. Below, we break down the most popular one piece swimsuit styles, how to choose the right fit and how to style yours from the water to dinner.
Why Choose a One Piece Swimsuit?
- It stays put. Swimming, volleyball, jumping off the boat – a one piece moves with you and stays in place.
- It doubles as a top. Add a skirt, wide-leg pants or denim shorts and your swimsuit becomes a bodysuit for lunch or a beach club.
- It flatters. Strategic ruching, cutouts and necklines can define your waist, lengthen your torso and highlight your favorite features.
- It still shows skin. Cutout and high-cut styles give you bikini-level drama with more support.

| Lace-up / strappy | Ties or criss-cross details | Adjustable fit and a sexy, playful look |
| Shimmer / metallic | Glossy or metallic fabric | Photos, vacations and beach clubs |
How to Find Your Best Fit
Check the torso length
The most common one piece fit issue is torso length. If the straps dig in or the suit pulls down at the chest, the torso is too short for you; if it sags or wrinkles at the stomach, it may be too long. Adjustable straps and tie details give you more wiggle room.
Match support to your bust
Halter necks, wider straps and ruched bodices offer more lift. One-shoulder and bandeau-style tops are best when you need less support or want a sleek, minimal look.
Use details to shape
Side cutouts create the illusion of a narrower waist, ruching smooths the midsection, and a high-cut leg visually lengthens your legs. Choose the detail that highlights what you love most.
Size with confidence
We carry sizes S–3XL across the store, but sizes vary by swimsuit, so check each product page for available sizes. If you are between sizes, consider the cut: suits with ties or lace-ups are more forgiving, while fitted cutout styles are best in your true size. For more curve-specific advice, see our plus size swimwear fit guide.

Caring for Your Swimsuit
Rinse your one piece in cool fresh water after every wear to remove chlorine, salt and sunscreen. Hand-wash with a gentle detergent, never wring it out, and lay it flat in the shade to dry. Heat and direct sun break down stretch fibers, so skip the dryer and keep your suit looking new longer.
One Piece Swimsuit FAQs
Are one piece swimsuits flattering on all body types?
Yes. The key is choosing the right details: ruching for smoothing, cutouts for waist definition, halters for bust support and high-cut legs for length. There is a one piece style that works for every shape.
How should a one piece swimsuit fit?
It should feel snug but not tight when dry, with no gaping at the chest or bunching at the waist, and the straps should stay put without digging in. Swim fabric relaxes slightly in water, so a close fit is ideal.
Can I wear a one piece swimsuit as a bodysuit?
Definitely. Solid, one-shoulder and cutout one pieces look great tucked into skirts, shorts or pants for beach bars and vacation lunches.
What is the difference between a one piece and a monokini?
A monokini is a type of one piece with large cutouts that make it look like a bikini connected by a strip of fabric. All monokinis are one pieces, but most one pieces offer more coverage.
Is a one piece better than a bikini for swimming?
For active swimming and water sports, a one piece usually stays in place better. For tanning, a bikini gives you more sun exposure. Many people pack one of each.
