The best swimsuits for women are the ones that stay put in the water, feel comfortable sitting on a towel and still look good in photos. Style matters, but fit, fabric and support decide whether you'll wear a suit for one vacation or for years.
This guide covers the main swimsuit shapes and who each suits, the fabrics and construction details worth checking, how to pick by activity and body, and how to care for a suit so it lasts. If you already know you want a particular silhouette, we link to deeper guides on one-pieces, bikinis and plus-size swim along the way.
How we chose: the criteria for a good swimsuit
Whether you are browsing women swimwear online or trying on suits in a store, judge every piece by the same questions.
- Support. Straps, bands and cups should hold you comfortably when you walk, swim and reach. Test with a few jumps and arm lifts in the fitting room.
- Coverage. Check the back, the sides and the leg line. Sit, bend and squat to make sure you feel secure.
- Fabric. A blend with enough stretch and recovery keeps its shape. Lining prevents transparency when wet.
- Construction. Look for sturdy stitching, flat seams, secure closures and, where relevant, removable or sewn-in cups.
- Chlorine and sun resistance. Some fabrics are made to withstand pool chemicals and UV better than others.
- Comfort when dry and wet. Fabric can feel quite different once wet. Check that straps don't dig in and bottoms don't sag.
The main swimsuit styles and who each suits
One-piece swimsuits
A one-piece offers full torso coverage and a streamlined line. It's practical for swimming laps, active beach days and anyone who prefers more coverage. Cuts range from classic tank styles to plunging necklines, cutouts and high-leg designs. See our dedicated guide to the best one piece swimsuits for a closer look.
Bikinis and two-piece swimsuits
Two-piece suits give you the most flexibility, since you can mix sizes for top and bottom, and they are comfortable in warm weather. Triangle, bandeau, underwire and sporty tops each give different levels of support. For more detail, see our guide to the best bikinis.
Tankinis
A tankini combines a tank-style top with separate bottoms. It offers the coverage of a one-piece with the convenience of a two-piece when you need the bathroom. It's a good option for traveling, for pool days with children and for anyone who wants more midsection coverage.
Swim dresses and skirted suits
A built-in skirt covers the hips and upper thighs while keeping a comfortable bottom underneath. These suits are popular for relaxed resort days and for those who want extra coverage.
Athletic and sport swimsuits
Designed for lap swimming, surfing and water sports, these have secure straps, a racerback or crossback design and fabric that holds up to frequent chlorine exposure. They aren't glamorous, but they stay in place.
Rash guards and swim tops
Long- or short-sleeve swim tops add sun protection and coverage. They suit surfing, paddleboarding and any long day in strong sun. Pair with swim shorts or briefs.
Plus-size and extended-size swimwear
Fit and support matter even more with fuller busts and curves. Look for wide, adjustable straps, underwire or molded cups, firm bands and ruching or lining where you want it. Our guide to the best plus size swimsuits goes deeper into sizing and construction.
Matching a swimsuit to your day
| Plan | Look for |
|---|---|
| Lap swimming | Athletic one-piece with secure straps, chlorine-resistant fabric |
| Beach lounging | Whatever you find most comfortable: bikini, tankini or one-piece |
| Active water sports | Racerback or sport tops, snug fit, rash guard |
| Family pool days | Tankini or one-piece, secure coverage for running around |
| Resort or vacation | Versatile suit that works with a cover-up and dinner outfit |
| Pregnancy or postpartum | Stretchy fabrics, supportive tops and adjustable features. Ask your doctor if you have questions about support. |
Choosing by body, comfort and preference
There is no body that needs a certain type of swimsuit. Use the points below as starting suggestions, not rules.
- If you want more bust support: Underwire or molded cups, wide straps and a firm band. A halter neck or adjustable ties spread weight.
- If you want a smoother midsection: Ruching, a tankini or a high-waisted bottom with a soft panel.
- If you want to elongate the leg line: High-leg cuts and bottoms with a higher rise at the hip.
- If you prefer minimal coverage: Adjustable string sides and triangle tops let you customize fit.
- If you have a short or long torso: Tops and bottoms sold separately help, as do one-pieces labeled with torso fits.
Choosing the best swimsuits for women: what to consider before you buy
Fabric and lining
Swimwear is usually a blend of nylon or polyester with elastane for stretch. Nylon blends feel soft, while polyester-based fabrics generally resist chlorine and fading better. A full lining helps prevent see-through areas, particularly in light colors. Check the fabric in daylight, then stretch it slightly, because thin fabrics can turn sheer when pulled.
Fit tests in the fitting room
- Bend over and squat to see how bottoms behave.
- Lift your arms and rotate your shoulders to test strap security.
- Check that the band lies flat and doesn't roll.
- Look for gaps at the top of the cups and the edge of the legs.
- If buying online, check the return policy, since hygiene liners are often not returnable.
Budget tiers
Entry-level suits are fine for casual trips or if you like to change styles regularly. Mid-range suits often deliver better fabric, more careful patterning and stronger hardware. Investment swimwear is worth considering if you swim often or need specific support, as the construction is usually more durable. Whatever you spend, rinse and care for the piece properly.
Care and longevity
- Rinse in cool, fresh water after each wear to remove chlorine, salt and sunscreen.
- Hand wash gently with mild soap, then lay flat to dry in the shade.
- Avoid wringing out the fabric or putting it in a hot dryer.
- Avoid sitting on rough surfaces like concrete or wood, which can snag.
- Rotate two suits during a trip so each can dry fully.
- Remove stains from sunscreen soon after wearing, since these can leave marks on light fabrics.
Swimsuit trends worth knowing, and what actually matters
Swimwear silhouettes shift from season to season, with high-leg cuts, cutout details, ruching, bold prints and minimalist solids all appearing across stores and beach clubs. Treat trends as flavor rather than a reason to buy. A classic solid in a flattering color tends to stay wearable for years, while a statement print is a fun addition once your basics are covered. Colors close to your skin tone can read as bare in photos, so test them in daylight. Dark neutrals and saturated colors hide wear and sunscreen marks better than white or pastels.
A simple swimwear wardrobe for one summer
You don't need a suitcase full of suits. Three well-chosen pieces cover most situations:
- A reliable main suit in a solid color that you can wear every day of a trip.
- A backup in a different style, so you can rotate while the first one dries.
- An activity piece, such as an athletic one-piece or a rash guard, if you swim laps or play in the surf.
Add a lightweight cover-up, a wide-brim hat and a bag that tolerates wet items, and you are set.
From the beach to dinner
Bathing suits can be the base of a whole vacation wardrobe. A cover-up, a pair of easy shorts and sandals take you from water to lunch. If your plans include walking around town afterward, throw a lightweight shirt over your suit and pack a pair of relaxed denim, and see our guide to the best jeans for women for fit tips. And remember sun care: a good SPF is part of every beach bag.
Common mistakes to avoid
- Ordering a suit one size too small hoping it will stretch.
- Ignoring torso length in one-pieces.
- Skipping the fit test with bottoms.
- Leaving a damp suit in a bag.
- Using a hot tub or heavily chlorinated pool regularly in a delicate lace or beaded suit.
Frequently asked questions
What swimsuit style is the most flattering?
There's no single answer, since flattering depends on what you want to feel. Choose the style with the support and coverage you like, then adjust details such as strap width, leg cut and rise. Comfort usually shows in how you carry yourself.
How should a swimsuit fit?
It should feel snug without pinching. Straps should stay in place, bottoms shouldn't ride up or sag and tops shouldn't gap. You should be able to move, sit and reach without adjusting constantly.
How long does a swimsuit last?
It depends on how often you wear it and how you care for it. Rinsing after wear and avoiding high heat extends life. Replace a suit when the fabric thins, the elastic loosens or the cups lose their shape.
What fabric is best for a swimsuit?
Nylon and elastane blends feel soft and stretchy. Polyester-based blends tend to hold up better against chlorine and sun. A lining improves coverage in either type.
Can I wear the same swimsuit for swimming and lounging?
Yes, if the support and coverage work for both. For frequent lap swimming, an athletic suit is more practical. For lounging, you have more freedom to choose looser or decorative styles.
In short
The best swimsuits for women combine support, coverage and fabrics that stand up to water and sun. Choose the shape that suits your activity, test the fit before you commit and care for it after each wear. For more ideas, browse our whole Swimwear section.
