Discovering the best swimsuit for your preferences can be tricky. Whether you're looking for a functional one-piece that'll stay in place while you surf or a sexy bikini for your next romantic vacation, we're here to help you find your next beloved swimsuit in your search.
We've rounded up suits for every preference — from the best high-waisted bikinis to the best underwire swimsuits for great support, to the best one-piece swimsuits with features that range from cut-outs to compression. If we had to choose a favorite, our top pick for the best swimsuits for women would be Summersalt for their comfortable and equally cute line of one-pieces and bikinis.

If you've seen everyone on your Instagram feed wearing a one-shoulder, color-blocked one-piece, there's a good chance that it's the iconic Sidestroke swimsuit from Summersalt. This particular swimsuit has 4.5 stars and over six thousand reviews on the website, with reviewers raving about how comfortable it is and how flattering the diagonal colorblocking and seaming is.
But that's just one piece in Summersalt's impressive and quality-focused swimsuit line. Insider did a full review of Summersalt's swim collection and we loved nearly everything we tried.

Andie's is a great place to pick the best swimsuits for practicality and quality. They're famous for their simple cuts, and thoughtfully-designed pieces. It's an excellent option for people all about beach volleyball, kayaking, and hopping on a board. You won't find any thong bikinis or daring cut-outs with Andie, but you will find pieces that last you many washes, are exceedingly functional, and come in fabric designed to be comfortable and supportive.

Frankie's Bikinis
Sizing options: XS-XL
Frankie's Bikinis is the ultimate it-girl brand. Their spokespeople include major trendsetters like Gigi Hadid and Sydney Sweeney who have rocked the brand's string bikinis and daring one-pieces in hyperfeminine prints like cherry bomb. Though Frankie's is one of the best swimsuit brands on the market right now, it might not be the best option for people who want a lot of support or are worried about their swimsuits being too revealing. I own their Tia Triangle Bikini Top and their Tia String Bikini Bottom in toile — and though the top is incredibly cute and I get lots of compliments, I don't wear the bottoms very often because of how tiny the coverage area is. Still, that makes it an excellent choice for a bachelorette trip to Miami or a sexy romantic getaway.

If you're looking for a suit that doubles as shapewear, then TA3 is a great bet for finding the best women's swimsuits. The shaping swimsuits by TA3 have gone incredibly viral on TikTok, with the hashtag amassing over 30 million views. The thing that sets these swimsuits apart from other brands is the unique tie-back that cinches in your waist.
The back of these swimsuits looks a little like the back of a corset, with criss-cross ties that keep the suit secure and emphasize the smallest part of your waist. We tried a few styles of TA3 suits and it was pretty amazing how effective the shaping aspect was. Plus, it's one of the best swimsuits for large busts that we've found.
See our full review of TA3 here to see how it looks on different body types.
Staff Pick
Flirty while still being supportive
TA3 Plungey SwimsuitThe deep plunge neckline is balanced by a fuller coverage rear for a subtly flirtatious design.
An ultra-flattering neckline
TA3 Squarey SwimsuitThe square neckline paired with the sculpting construction will create a great silhouette.

Staff Pick
Sexy and lacey
TA3 Lacey SwimsuitSmoothing and sculpting meet comfort in this adjustable one-piece.
Cuup
Sizing options: Tops come in traditional bra sizing, up to an H cup. Bottoms come in XS-XXXL.
We love Cuup's bras and they recently came out with a line of some of the best women's swimsuits. Cuup is the perfect place to go if you want underwire bikini tops that are available in your exact bra size. These tops range from 30AA to 44H, while the bottoms come in sizes XS to XXXL.
Right now Cuup only offers three types of tops — a balconette, a plunge, and a scoop neck. Likewise, their bottom selection is limited to a cheeky bikini cut, a mid-rise, and a high-rise. But what they lack in variety they make up for in quality and exact sizing options.
See our review of Cuup's plunge bra, an additional silhouette in their swimwear collection.
Helen Jon
Sizing options: XS-XL
Most brands use fit models who wear only the smallest sizes to construct their garments. This means that most of what you buy is made for the proportions of a literal model. But not Helen Jon. They fit their swimsuits on their own employees, so that each piece is made for the proportions of a normal, non-model. So if you're wondering why these suits fit amazingly well, you've got your answer.
Read our full review of Helen Jon to see why this is one of the best women's swimsuit brands right now.
Hermoza
Hermoza is the perfect brand for swimsuits that are relatively modest, yet still stylish. They have vintage-inspired picks like belted one-pieces, high-waisted bottoms, and halters with waist ties. Personally, I love wearing this brand for family-centric events in the summer where I don't want to be showing too much skin, even if I'm in a bikini. But the pieces are so cute that I wear them to beach days with friends.
Skims
Sizing options: XXS-4XL
If there's one thing Skims is incredible at, it's sexy basics. Their pieces are thoughtfully cut to be the most flattering, and their swimsuit collection qenuinely exemplifies their commitment to making you look the best with less. We love their flirty, simple bikinis that are reasonably priced for the quality.
Everlane
Sizing options: XXS-XXL
Everlane is one of our favorite places to shop for modern basics. We did a full review of Everlane's most popular styles and can confirm that everything they make is high-quality. Their swim line is no different and might be one of their standout collections.
Our Executive Editor, Sally Kaplan, was particularly impressed with the Square-Neck Bikini Top and The High-Rise Hipster Bottom: "Each piece had just the right amount of stretch and compression — no digging and no underwire — and I couldn't tell the recycled material was any different than usual swimsuits. I will definitely be buying another style soon."
See our Everlane swimwear review to see more of our favorite pieces that we tested.
Vitamin A
Sizing options: XS-XXL
Vitamin A is a swimwear brand based and made in California. They're one of the best places to shop for women's swimsuits that are on-trend and unique. Unlike some brands on this list that focus on classic colors and designs, Vitamin A has many fun choices from florals to stripes. They even have a special section for ultra-supportive tops designed for large busts.
Amazon
Sizing options: Various
You can get everything on Amazon — including some of the best women's swimsuits. Cupshe is one of the site's immensely popular swimwear brands, carrying everything from compressive one-pieces, to string bikinis, to gauzy cover-ups for the beach. Plus, one of the big perks of Amazon is the many thousands of reviews that will give you insight into the body types each piece suits.
See our piece on the best swimsuits on Amazon for more of our favorites.
Solid & Striped
Sizing options: XS-XL
Solid & Striped is on the pricier side, but the artful designs make these pieces look super unique and luxurious. This is one of the best places to shop for swimsuits if you're a bit daring since some pieces in this line lean more toward the sexy — like this ultra high-cut one-piece and this crochet string bikini. In addition, they have a robust selection of cute cover-ups.
Solid & Striped also made our list of the best one-piece swimsuits.
Swimsuits for All
Sizing options: 4-34, varies
Swimsuits for All gets an A+ when it comes to size inclusivity. These swim pieces are specifically designed for plus-size bodies and feature lots of thoughtful details, like underwire, ultra-adjustable fits, and a section where you can shop by body type to find the perfect suit for you. Swimsuits for All also have silhouettes that are hard to find on other sites — like swim dresses and shortinis (swimsuits featuring shorts).
See our full review of Swimsuits for All to see a more in-depth overview of the brand.
Hunza G
Most of Hunza G's swimsuits are made from their signature seersucker material that is textured and super stretchy. They are so stretchy that their swimsuits are one-size-fits-most. The flattering fabric is also comfortable and thick enough to stay put.
Hunza G's great separates also made our list of the best high-waisted bikinis.
L*Space
Sizing options: XS-XL
L*Space is a trendy label with lots of celebrity devotees. They specialize in simpler pieces in vibrant hues that catch your eye right away. Because these pieces are so fun and simple, lots of them can double as a bodysuit or a bralette — no one will ever know.
