Pair these with every one-piece and bikini you own.

You've filled your beach bag with sunglasses, SPF, and more than one beach read. You've edited down your swimwear collection to most essential one-pieces and high-waist bikinis, with a few summer sandals to get you from the parking lot to the cabana. All that's left to complete your swimsuit season lineup is the perfect cover-up.

Regulars on the shores of Tulum or the bleached steps of Santorini know the best swimsuit cover-ups don't hide your bikini or maillot. They're the finishing touch on a resort-ready outfit and, practically speaking, they're the layer you need to slip into an air-conditioned café between tanning sessions. To find the best swimsuit cover-ups, look for breathable fabrics like linen and gauze to keep you cool, plus relaxed fits that won't cling to a damp swimsuit. As for the look? Summer 2022 collections have a mix of tiered dresses, wraparound skirts, and caftans to accentuate your swimsuit. Go for Frankie Shop or Bondi Born's matching button-down sets for an all-in one outfit or lean into the crochet comeback for a modern boho feel at Cult Gaia or Marysia. One of the following 30 swimsuit cover-ups will speak to your vacation style—and you'll want to wear it beyond the beach or pool.

All searches for the best swimsuit cover-ups lead to caftans. These dresses are the epitome of vacation wardrobing: They're airy and free-flowing with maximum coverage, exactly what you want to wear when lounging poolside or exploring your resort town. Err on the side of neutral tones and understated nautical details for a caftan you'll use season after season, like Eres's striped version.

If you have yet to join the Emilio Pucci revival, its beachy caftans are the best place to start. The kaleidoscope swirl print is so distinctive, this dress doesn't need any extra embellishment to stand out.

Three Graces is a crowd-pleaser for longer caftans in the highest-quality linens.

Neutral tones give this caftan a laid-back feel, even with all those floral details.

Tory Burch's blue seersucker caftan, embellished with tiny tassels, can go from Martha's Vineyard to Mexico and back.

What started as a summer trend has become a fully-blown category: the relaxed shirt and short set. These sets give you full coverage over your swimsuit and double as an unruffled summer outfit. Frankie Shop's Liu shirts and shorts are often Instagrammed in city settings, but they're just as suited to wearing over a swimsuit with a flat sandal.

Embroidered finishes and a dramatically oversized top mean you can wear this matching set on and off the boardwalk.

If you're craving a dressier feel from your poolside co-ords, the wrap finish on Bondi Born's set should do the trick.

Want the feel of the caftan with the structure of a daytime dress? Some summer dresses can double as swimsuit cover-ups—it just depends on the fabric and cut. Tiered and shift shapes are your best bets for longer cover-ups that are a little more polished, like this linen dress by Lemlem.

With dreamy tiers and an open back embellished with relaxed bow, who wouldn't fall for this romantic cover-up?

This simple shirtdress has hidden details that make it a vacation necessity. The double-gauze fabric is some of the most lightweight on the market, ideal for blazingly hot days. Side-slits and a long line of buttons mean you get extra ventilation and you can style it as a breezy duster jacket. Best of all, it's available in up to size 3X.

Dôen's etherial sundresses are as ideal for wearing over a swimsuit as for swanning about your home. The look goes heavy on feminine details, like ruffles and painted floral prints, while the feel is softer than you find in most cover-ups. (Editor's note: Dôen's new, coordinating swimwear line is also very good.)

Cutouts and cover-ups aren't mutually exclusive. Either the waist-defining slits on this dress align with your bikini, or they create a color block moment over a solid one-piece.

Crochet is for so much more than music festivals. These open knits have a decidedly beachy feel worth buying into, especially if a trip to a seaside resort is on your horizon. Cult Gaia's fitted crochet dress shows off a peek of your swimsuit with its semi-sheer knit and open back.

Akoia Swim's halter-neck dress isn't just a perfectly laid-back knit—it's also plastic-free, making it a more eco-friendly option.

This easy dress has an open back to balance out the long, scallop-edge sleeves.

Marysia's crochet dress has a more opaque knit, for the woman who wants a textured cover-up but doesn't want to reveal her whole swimsuit.

Neutral tones may dominate the crochet comeback, but you can find unexpected colors in the same open knits. PatBo's emerald green cut-out dress hits on the handmade trend and looks one-of-a-kind.

Cotton or gauze, linen or terry, mini dress cover-ups are an essential. Summery details like the braided straps and floral print on this Ulla Johnson dress make them distinct from the dresses you'll wear when you're back from vacation.

This cover-up has the same relaxed feel as those coordinating shirt sets, but the mini hemline and gauze fabric make it feel new.

White linen with navy embroidery is a fail-safe vacation style, including your next cover-up.

The babydoll shape and adjustable straps make Solid & Striped's mixed-print dress an easy-on, easy-off option. And yes, you'll want the matching swimsuit to go with it.

Swap your flip flops for a high-heel sandal, and this cotton poplin cover-up is appropriate for a sit-down dinner (indoor or outdoor).

Wraparound skirts known as pareos and sarongs are the best swimsuit cover-up when you want to show off your swimsuit. Start with Lemlem's sunny printed sarong to contrast a solid one-piece, then add a raffia tote.

The psychedelic wavy print on Onia's pareo will stand out in a sea of solid cover-ups. Its longer length also lends it to folding and tying in different ways, including around the waist as a skirt or under your arms as a dress.

Agua Bendita's pareos show off the designer's Colombian roots through their gorgeous prints. Wear this one with a solid bikini to make the pattern pop.

This summer, Wardrobe.NYC is channeling its capsule wardrobe magic into a resort edit. The brand's sarong folds beautifully over any swimsuit, and the fabric is softer than anything else you could pack.

With two-day shipping, this printed sarong will arrive just in time for your flight to Cancún.
