The 2025 Swim Report—Here's Every Major Trend to Know

At the onset of summer, we're thinking about swimwear and the key suitcase-worthy styles to shop for vacation this season. For summer 2025, we are seeing some clear trends taking shape. Many of them are connected to what is happening in fashion in a larger sense. The gingham prints that have been returning to everything from kick-flare pants to skirt sets are also appearing on bikinis. Personality-infused fashion—often seen on the street style scene with pillbox hats and bag charms—is entering swimwear in the form of stone-adorned straps and hardware buckles. The pendant necklaces that are taking over on the style set are also a key accessory to style with swimwear.

Other trends feel like a continuation of what we saw last summer with some subtle tweaks. In 2024, we saw the rise of printed designer motifs, and that is only expanding. Martini green was a key color last year and has extended to earthier tones. Others feel fresh for summer 2025, especially new riffs on the classics. Nautical stripes are getting a refresh, and one-pieces are appearing in deep-plunge silhouettes. Ahead, shop the seven biggest swim trends to know for summer 2025.

The piece every fashion insider is clamoring to get in their closet for summer? A pendant necklace. Pieces from brands such as Juju Vera and Le Sundial have taken on IYKYK status and are selling out faster than they can be restocked. While it started out as a jewelry trend worn with everyday clothing, it is now making its way to the vacation set on holiday in the South of France and the runways in the collections of Chanel and Chloé. We're expect to see pendant necklaces with tassels and charms layered over swimwear all summer long. It's a swimwear trend that isn't actually about the swimsuits themselves—just how to style and accessorize them.

These aren't your basic black bikinis—they're statement pieces disguised as instant classics. Designers are finding ways to spruce up longtime favorite swimsuit silhouettes. Think a triangle bikini top with a bit of beading on the straps and a classic leopard one-piece with an unexpected metallic clasp in the back. You deserve a swimsuit collection that feels more editorial than athletic. It's less about blending in at the beach and more about turning heads from the towel to the cabana bar.

Deep, plunging necklines are a common thread we're seeing in the realm of one-pieces for summer 2025. In past seasons, contrast-trim designs and simple sporty silhouettes took over, but now, we're seeing a shift to styles that are sexier and more skin-baring yet elegant. The swimsuits are often styled with wide-brim hats, classic sunglasses, metal jewelry, and sarongs tied at the waist that dial up the sense of glamour the plunging one-pieces evoke.

The print that is more commonly known for its contribution to summer picnic dresses and vintage Brigitte Bardot references has officially made its way to the swimwear market. Gingham is popping up even in designer collections that you wouldn't expect it to be in—yes, that is a Celine gingham swimsuit. Brands are making this throwback print feel especially fresh in modern cuts, like high-waisted bikinis and ruched one-pieces. This is a trend that simply blurs the line between sweet and cool, offering a playful take on classic style that looks just as good poolside as it does under an oversize button-down at lunch.

If you must wear a solid color to the beach this season, let it be this one. Neutral swimwear isn't new, but the palette has expanded into deeper, richer territory. Clay, sienna, sage, and espresso are dominating the racks, and they bring a certain effortless polish to your beach-day lineup. Bonus points if you pair them with leather sandals and gold jewelry—it's giving low-effort luxe in the best way. These grounded hues are the swim equivalent of a really good capsule-wardrobe piece: timeless, wearable, and quietly confident. Wear one and you'll glimmer against the sand.

Nautical swim has always been a summer staple, but this season's version feels a little more refined. Its original heyday was more of a ready-to-wear moment—e.g., Audrey Hepburn wearing a striped collared shirt in the '50s—but now, it's set to be booming in swimwear collections. Think sleek one-pieces with strategically placed stripes and barely-there bikinis with a sailor-inspired twist. There's a retro charm to it, especially when paired with cat-eye sunglasses and a crisp white linen cover-up, but it still feels modern enough to wear in Saint-Tropez or at your friend's rooftop pool party.

If it looks like something a stylish woman might've worn on a Mediterranean vacation in 1974, you're right on track. Iconic prints from brands such as Pucci, Missoni, and Burberry are staging a full comeback—swirls, chevrons, and checks included. Whether you opt for a retro halter one-piece or a string bikini with vintage energy, these swimsuits are a nod to the past in a way that feels incredibly now. Just add oversize sunglasses and a headscarf for the full effect. Bonus points if you dug through a vintage store to find a chic cover-up.
