The best swim dresses solve the most annoying swimsuit dilemma: finding something that's cute, comfortable, and actually offers a little extra coverage. For as long as I can remember, I've been stuck in swimsuit limbo: The stylish swimsuits never have enough coverage, and the modest swimsuits tend to look like they were designed to make you disappear. But swim dresses have officially entered their comeback era — and the new versions are anything but frumpy.
In fact, I'd go so far as to call swim dresses one of the up-and-coming swim trends for summer 2026. Lately, we've spotted an influx of swim dresses and swim skirts on the NYC fashion crowd at media events and out in the Hamptons, and it makes sense: They're feminine, flattering, and secretly practical. They're also the ultimate boat day outfit, since they give you the ease of a swimsuit with the polish of something you'd actually want to be photographed in.
After researching dozens of options and testing several myself, I found a few swim dresses that strike the right balance between function and fashion. Whether you're looking for a fun patterned pick for a resort vacation, a supportive plus-size style, or a budget-friendly option, these are the best swim dresses for every need.

Best overall swim dress: Garnet Hill Shoreline Side-Slit Swim Dress
I've only owned a few items from Garnet Hill, but the quality has impressed me every time — these are pieces that hold up well in the wash, and tend to last me for years. The Shoreline Side-Split Swim Dress is no exception, but that's not all there is to love about it. With a surplice-style V neckline, wrap-like skirt, and side slit, it's the kind of silhouette that flatters every body type. Plus, it's designed with a smoothing power-mesh for extra shaping and support. As someone with a large bust (as in DD cup), I also felt super secure in the built-in shelf bra with sewn-in soft cups.
The fabric is soft, lightweight, and most importantly, offers UPF 50+ sun protection. As an added bonus, this swim dress is also machine washable.
Best patterned swim dress: Old Navy Matte Side-Tie Swim Dress
This swim dress is a perfect example of fashion-meets-function. It's machine washable and offers sun protection, but it also comes in a number of on-trend prints — like brown zebra and blue ditzy microfloral.
As far as swimwear goes, this Old Navy swim dress has quickly become one of my go-tos for casual pool days and beach outings. It may not provide as much support and compression as some of the other options, but it's lightweight, comfortable, and stylish enough for everyday use — and the square neck, wide shoulder straps, and wrap skirt give it timeless appeal.
Best swim dress that doubles as a real outfit: Lands' End
The Land's End Square Neck Smocked Mini Swim Dress is one of those rare swimsuits that genuinely looks like something you could wear beyond the pool. At first glance, it reads more like a cute summer mini dress — or even a romper — than traditional swimwear, thanks to the square neckline, smocked bodice, and flouncy skirt. It is definitely on the shorter side, so don't expect tons of leg coverage, but that also keeps it feeling playful, youthful, and not at all frumpy.
The smocked top is more than just a cute design detail, too: it has enough stretch and structure to comfortably support larger busts without feeling stiff or overly sporty. Overall, it's sweet, feminine, and super cute — the kind of swim dress you'll want to throw on for pool days, beach vacations, and any moment when you'd rather look like you're wearing an actual outfit than a swimsuit.
Best stylish swim dress: Venus St. Tropez Swim Dress
If you're on the hunt for a resort-ready swim dress that'll stand out, look no further than this style — which features a playful paisley pattern and sweetheart neckline.
Reviewers rave about the shaping support, which comes from a control lining. And if you're large-busted, you're bound to appreciate how the St. Tropez Swim Dress has molded cups and wide adjustable straps. Criss-cross gathering across the bust and ruching in the bodice add some nice texture, while the flared mini skirt offers movement and moderate coverage.
Best convertible swim dress: Land's End Sculpting Bandeau Lace Back Mini Swim Dress
I'm all about versatility when it comes to style, so it should come as no surprise that I live for anything convertible — because I get multiple looks in one garment. This Lands' End swim dress has removable straps, which is great when I'm in the mood for an off-the-shoulder moment. Bandeau-style tops are typically a disaster for my fuller bust, but that's not the case here. I found that the sewn-in soft cup bra provided pretty impressive lift and support.
I know I'll get a lot of use out of this swim dress, too, because it's made with a special type of spandex, which is resistant to damage from chlorine, sunscreen, and sweat. It's also UPF 50 fabric, which has the Skin Cancer Foundation's seal of approval for sun protection (only for areas covered by the material).
Above all, though, this swimsuit is exceptionally flattering. The adjustable lace-up back cinches my waist while also adding some visual corset-inspired intrigue, and the sculpting panels provide targeted areas of compression to enhance curves.
Best plus-size swim dress: Land's End Smoothing Square Neck Ruched Swim Dress Swimsuit
With regular, petite, plus-size, and long-torso options, this swim dress is definitely one of the most size-inclusive I've come across. Reviewers claim it's well-made with durable fabric that stands the test of time. The chlorine in swimming pools is notorious for breaking down elastic swimsuit fibers, making them more vulnerable to tearing, stretching out, and losing their shape. This swim dress was thoughtfully constructed with a specific type of spandex that's resistant to breaking down due to not only chlorine, but also sunscreen and sweat.
According to the dozens of happy customers who've bought the Smoothing Square Neck Ruched Swim Dress, it also highlights all their best assets — while camouflaging the areas they're less confident about. Cap sleeves offer subtle coverage, while the modest square neckline visually balances out wider hips, accentuates the bust, and elongates the neck.
Best supportive swim dress: Swimsuits For All High Neck Wrap Swim Dress
Finding a swimsuit with enough support for my DD-cup bust is no easy feat. This High Neck Wrap Swim Dress holds me up exceptionally well, thanks to the adjustable straps and the encircled shelf bra with wire-free, molded cups. And the criss-cross neckline doesn't just offer visual interest but also much-appreciated additional lift. Meanwhile, the power mesh lining provides ample compression, making this feel like swimwear and shapewear in one.
A fit-and-flare silhouette and ruched wrap-front detailing give this swimsuit the timeless, chic appeal of a little black dress. I felt like a million bucks wearing this for a family pool day, and even found myself wondering: Is there a world where this could pass for a regular dress?
Best budget swim dress: Blooming Jelly Women's One Piece Swimsuit
Thousands of customers have left five-star reviews for this swim dress, saying it makes them feel both comfortable and confident. That's no surprise, given the flattering ruching in the bodice, the cute side-tie detail, and the eye-catching gold metal accents. The slit lends a flirty twist, while the adjustable straps ensure you get adequate support in the bust.
This swim dress not only comes in a wide range of colors and patterns, but it's available up to size 4XL. And despite the affordable price tag, it's surprisingly well-made: Because laser technology was used to make the hem, you won't have to worry about any fraying.
Best shaping swim dress: Shapellx Smart Sculpt All-In-One Mesh Wrap Shaping Swimsuit
Shapellx is known for its size-inclusive, revolutionary shapewear — but don't sleep on their swimwear. The brand's corset swimsuit was a huge hit with Business Insider's Colleen Sullivan, who raved about the "made-for-you" fit and gentle compression that offers a "held-in feeling" without restricting breathing or movement.
But what sets the All-In-One Mesh Wrap Shaping Swimsuit apart is the attached mesh sarong — turning it into a travel-friendly two-in-one look. The skirt provides extra coverage when you want to grab some beachfront drinks at the resort bar, but you can also lift it to reveal a ruched panel and a more traditional one-piece.
This swim dress also doubles as shapewear, with inner mesh that smooths out your torso — but customers claim it's surprisingly comfortable thanks to the breathable fabric and four-way stretch. Removable padding and wide adjustable straps allow you to achieve customized support, while the keyhole bust cutout and hip side-ties add some feminine flair.
Best modest swim dress: Aleumdr One Piece Swimdress Swimsuit
If you find that the skirt is just a tad too short for your liking on most swim dresses, this one provides the perfect solution — plus, it features a higher neckline. Regardless of the simple and modest design, though, it’s super chic and flattering: The split hem adds a slightly playful touch while ensuring ease of movement. From classic neutrals to rich jewel tones and bright florals, this swim dress also comes in a wide range of shades and prints.
Another practical detail: This swim dress is made with quick-drying fabric. This is actually a noteworthy perk — after testing a number of swim dresses, I’d say my main pet peeve is that most of them take forever to dry.
Did I mention there are pockets? Those definitely come in handy for stashing sunscreen, chapstick, and other summer must-haves.
