It’s not hard to see why Amazon shoppers love this two-piece swimsuit. From the bustier top to the high-waisted bottoms, it’s a timelessly stylish duo that offers endless mix-and-match potential, considering you can choose between dozens of colors and prints. Keep in mind that the set seen here has convertible straps, but a few options feature self-tie halter straps instead. Either way, this set is backed by more than 8,000 five-star ratings, with plenty of people praising the impeccable fit.

Positive review: “[...]this product is so well made, great material, both the top and bottom give you great support and it’s comfortable. And the straps on the top are adjustable. Each day at the beach I changed them from spaghetti strap, criss-cross, and then halter style. Bonus, it washes really well on cold, I let mine hang dry.”

Here’s another classic bikini top you can mix and match with a variety of bottoms (like the brand’s high-waisted or ruffled options). The curved push-up cups feature side boning, underwire, and built-in wings for structure, but the ruched overlay keeps it from looking too much like lingerie. Plus, the adjustable straps can be converted to cross-back or halter, so you can get several different looks from this one top.

Positive review: “The BEST fitting bikini top I have ever purchased. I have a quite a small chest (32-AA/A) and this fits perfectly with absolutely no gapping. It gives perfect lift to what little cleavage I have. I ordered in more colors. Extremely true to size and well made. Highly recommend.”

• Available sizes: 32A — 40D

Because this tankini set has a skirted bottom, it looks more like a swim dress than separates. This pair is not only great for those who want more coverage, though — it’s also a perfect choice for travel, as it can double as an everyday outfit if you don’t want to bring a change of clothes to the beach. In terms of design details, the sweetheart neckline is supported by an underwire and adjustable, convertible shoulder straps, while the sporty skort has a zippered pocket and built-in panty.

Positive review: “The top provides support in a pretty way, and the combo tankini + skirt makes this look and feel like an OUTFIT, not just a swimsuit. The skirt looks like a normal tennis skirt. I can wear this around during the day as I travel to/from the beach, without needing a coverup to go into shops or restaurants.”

The marble print on this bikini set is one you’ll be seeing a lot this season, according to runway shows. But the stylish print isn’t the only thing that’s trendy about this bikini — the plunging, architectural neckline, the bottom’s high-cut sides, and the low-coverage silhouette are equally on-point. Best of all, it comes with a matching, semi-sheer, sarong-style cover-up.

Positive review: “SUPER CUTE! love the ensemble all together looks just like the picture :) true to size!!!”

• Available sizes: Small — X-Large
• Available colors/prints: 13

It may be slightly kitsch, but you can’t deny how cute this mermaid-inspired tankini set is. Even without the metallic scale print (it also comes in botanical prints and solid shades), the silhouette is super playful, featuring a sweetheart neckline, a front bow, and a swingy peplum hem. The straps can be fully removed or converted, and it comes with a matching, high-rise bikini bottom with a ruched front.

Positive review: “I almost never write a review. But this suit deserved it. If you’re worried about buying a bathing suit on the internet, don’t fear this one. It’s true to size, great quality [...] it’s difficult to find a bathing suit that actually makes me feel confident. This one did. And I’m buying a second one ASAP.”

• Available sizes: Large — 5X-Large
• Available colors/prints: 6

If you want the support of an underwire without the look of one, consider this one-piece swimsuit. The wired cups are lightly padded and virtually undetectable. Instead, you’ll just see a chic crossover front with ruched sides, and in back, doubled-up criss-cross straps. Choose from a few bright or neutral shades, but keep an eye on the images as you shop — some may have single, convertible straps instead of double.

Positive review: “La Blanca Bathing Suits have never let me down! This is the 4th one I've owned and love it! It has great support, adjustable straps, and rouching. Great quality!”

• Available sizes: 0 — 16; 16 Plus — 22 Plus
• Available colors/prints: 8

How chic is the bikini top? It’s not just for show, as it’s made with a few details to ensure the perfect, comfortable fit. Take, for example, the two hooks in the back, each with multiple rows of adjustment for customized wear. The underwired cups and longline silhouette offer support, but the bustier seaming is pure fashion. If you decide to wear this as a styling piece, like as a bralette over a white T-shirt, who could blame you? But if you reserve it just for swimming, you can get the matching bottoms, too.

Positive review: “Fits perfect. Normally cup sizes run too small, but this is spot on. I am so happy to find a top with full coverage (nearly impossible for us busty girls) that is also comfortable and cute. Shoulder straps offer a lot of “slack” so it provides tons of adjustments. And with the 2 separate hooks on the back, plus underwire- it provides a ton of support. Will definitely be ordering this brand again!”

• Available sizes: 34C — 44D

Dive into this pretty tankini set, which has a gorgeous, fluttery silhouette. Its molded underwire cups are joined by a pretty twist detail, and the entire silhouette is covered with a flowy animal print (though a few floral prints and some lace options are available, too). In the back, you’ll find adjustable straps and two hooks for an ultra-customized fit. It comes with a basic, full-coverage bikini bottom, but feel free to substitute with your own.

Positive review: “Finally!! I’ve been looking for years for an underwire tankini top that provides support, lift, and covers the sides of my breasts. This tankini top is perfect! I just ordered another one and this is the only time I have ever bought two of the same bathing suit tops (I ordered a different color).”

• Available sizes: 12 Plus — 24 Plus
• Available colors/prints: 6

This one-piece swimsuit is the epitome of timeless style. Whether you choose to wear it with the included optional straps — which are adjustable and can be worn over the shoulder, criss-crossed, or halter-style — you’ll enjoy the support of underwire cups with extra push-up padding. In addition to the chic animal print shown here, you can choose from a few bright, colorful geometric patterns, florals, or even a kitschy American flag design.

Positive review: “[...] When I tried it on and it fit like a glove while also supporting me it felt like the heavens had finally opened!! This suit gives me great support in the chest area as well as support on my stomach! Please ladies give this suit a chance! I wore mine with the straps which are adjustable and I was comfortable ALL day! Also, let me add how beautiful these colors are! It looks honestly just like the picture!”

• Available sizes: 10-12 — 18-20
• Available prints: 11

Looking for a swimsuit that offers guaranteed support? Consider this one-piece from Freya, a popular bra designer that specializes in a broad range of cup sizes. Featuring bra-like foam cups with underwire, supportive side boning, and thick, adjustable straps, you’ll feel super secure from the beach to the spa and everywhere in between — plus, the fabric is made to combat chlorine, so it’ll last longer, too. With ruched sides and a front bow, this swimsuit is stylish enough to make an impact but timeless enough to look good for years to come.

Positive review: “I was very grateful to find a cute swimsuit to accommodate my 36H (or 36FF in UK sizing) bust that wasn't overly expensive! It is so hard to find a swimsuit with an underwire to provide the lift and support I need, let alone one that comes in my exact bra size. The suit is comfortable, stays in place, and has full coverage in the butt, which is important to me as I have sensory issues and can't stand the feeling of "cheeky" underwear/bottoms.”

• Available sizes: 30C — 32GG

The rainbow pattern on this bikini set brings some fun surfer vibes, while the bandeau-style top and ruched detailing on both the top and bottom offer a spin on your typical two-piece. Adjustable straps, underwire, and padding all offer lift, definition, and enough support even for swimming and water sports, according to reviewers. If you aren’t a fan of this rainbow print, you have 20 more colors and patterns to choose from, like color-blocked and gingham options.

Positive review: “I’m a huge skeptic when it comes to buying swimsuits online but this one is fabulous! [...] Fits great in all areas. Straps can be worn like a cami or crossed in the back! Will buy more!”

• Available sizes: Small — XX-Large
• Available colors/patterns: 21

Between the underwire, molded cups, adjustable straps, and hook-and-eye closure, this bikini top offers ample support. But it doesn’t skimp on style either: The wrap detail in front is pure elegance, while subtle cutouts on each side hit on another major trend this season. This would look so chic paired with a sarong, strappy sandals, and some gold jewelry for poolside cocktails.

Positive review: “Good experience shopping with this vendor and product exceeded expectations.”

• Available sizes: 32-34C — 40-42F

Doesn’t this swim set drip with Marilyn Monroe vibes? From the molded cups to the halter neckline, the high-waisted bottoms to the ruched design, this suit is so retro-chic, but still perfect for modern poolside hangs. Lightly padded cups add structure, while a back hook keeps things secure. The lipstick red and polka-dot set pictured above is an overwhelming fan-favorite, but plenty of shoppers like the other color and print options, like stripes, florals, and other polka-dotted colors.

Positive review: "Simply…the BEST bathing suit I have ever owned…period. It was as if this swimsuit was tailor made exclusively for me. I have a hard enough time as it is finding a swimsuit that fits, and that’s when I try on every one in an actual brick-and-mortar store. I took a leap of faith and ordered a bathing suit online for the first time. I am so happy I did. The 5 star reviews and photos speak for themselves. This is a FANTASTICALLY PERFECT bathing suit.”

Unlike most barely-there string bikini tops, this one is equipped with an underwire, so you’ll feel both hot and supported. Because it has such a classic, chic silhouette, you could wear it with any number of bikini bottoms already in your arsenal (though if you prefer a matchy-matchy look, you can find the coordinating bottoms here). In back, the shoulder straps loop through the band and act as a closure, which means you can adjust your fit in a number of ways, whether you do a simple knot or something more detailed, like an eye-catching braid. The underwire cups also have removable padding and power-mesh lining, so they’ll offer the look of a basic triangle bikini but the support and separation of a bra.

Positive review: “This fits very similar to a bra, imo. It has great support and is perfect for active swimming or water/beach activities. It’s cute and flattering as well.”

• Available sizes: D — F

Swimsuits don’t get much chicer than this black tankini top. Simple yet elegant details, like a pretty twisted front and sweetheart neckline, ensure you’ll keep this piece in your lineup for a long time. Meanwhile, removable cups, an underwire, and adjustable straps offer coveted support. You could even wear it in lieu of your usual black tank top year-round to get more wear out of this gorgeous piece; but for the beach or pool, pair it with the brand’s equally classic high-waisted bikini bottoms.

Positive review: “I would definitely recommend buying this swim top! It’s comfortable, doesn’t ride up, straps are adjustable (I love that) and the cups seem pretty accurate in size. I plan to buy another!”

• Available sizes: 34B/C — 40D/38DD
• Available colors: 5

Between the V-shaped underwire, one-shoulder silhouette, and high-cut bottom, this bikini set checks off every swimwear trend you’ve seen on your grid lately. This isn’t the most supportive option on this list, but the adjustable shoulder strap offers some customization. Complete the influencer-inspired look with a pair of chunky cat-eye sunglasses and a silk headscarf.

Positive review: “Being a D cup I CAN NOT do strapless but something possessed me to buy this bikini and I'm so glad I did!! The one strap gives the feeling of security and the sholderlessness on one side looks fabulous. The material is thick and lined. 10/10 would buy again.”

• Available sizes: Small — X-Large
• Available styles: 22

Amp up the texture with this underwire bikini top. With a tonal lace overlay, it’s an understated but interesting alternative to a bold print; and while the textile and shape may veer into lingerie territory, it stays swim-appropriate with beaded front tassels (and the matching bikini bottom has sheer sides to complete the beachy look). You’ll still get bra-like support with underwire contour cups, foam lining, reinforced side boning, adjustable straps, and a snap closure in back.

Positive review: “I am absolutely in LOVE and finally feel confident enough to go out and be secure! I am absolutely flabbergasted with this brand. I shed happy tears over something as simple as a correct fitting top. I highly suggest Freya. You will not be disappointed. I will no longer purchase any other brand.”

• Available sizes: 30D — 38G
• Available colors: 11

This tankini set is nothing but goddess vibes. It has the fit of a supportive bikini top — with underwire push-up cups, a center bow, and self-tie halter straps — and it’s finished with a printed, semi-sheer handkerchief hem that floats like a dream when you move. Plus, it comes with matching full-coverage shorts no matter which color or pattern you choose.

Positive review: “Lots of compliments about how cute my swimsuit was. Very well made, and I would know because I sew and know what makes good quality. Fabric is beautiful. Length of skirt, on me, was to my knee….. but I’m 5’3”. Love that it covers my thighs.”

• Available sizes: Small — XX-Large
• Available colors/prints: 11

If you’ve tried Calvin Klein underwear, then you already know this bikini top is soon to become your new favorite. With its molded balconette cups and ruched detailing, the front has a timeless aesthetic, while the opposite side has a few customizable features, like ties that can be arranged in any way you can dream up, like twisted, crisscross, or just over the shoulder. Don’t forget to grab the matching high-waisted bottoms.

Positive review: “This bathing suit top is so comfortable [...] I can swim/lay out in the sun/walk around and not be fidgeting with it constantly! The fact that you can wear it three different ways is great!”

• Available sizes: X-Small — XX-Large
• Available colors/prints: 5

This fun yet sophisticated swimsuit updates the classic one-piece silhouette with a chic notched front. It's deceptively supportive, too, as the foam cups and built-in underwire are nearly imperceptible thanks to the subtle, wrap-style overlay at the bust. Although the straps aren’t adjustable, they’re padded for extra comfort. Take your pick from several floral and geometric prints, or go with one of several solids available.

Positive review: “This is my absolute favorite swimsuit! It lasts for years, the color holds up well, and fit is fantastic. It's comfortable, cute [...] but still covers enough that you can do almost anything in it.”
