The Swim Trend Everyone Stylish Is Packing: Swim > Swimsuits & Cover-Ups: Bikini Bottoms: Side Tie

If Spring 2026 has a defining swimwear mood, it’s this: vacation dressing is getting playful again. Not loud. Not overstyled. Just a little more fun. After seasons of sleek athletic-inspired swimwear dominating the conversation, fashion is rediscovering the charm of details that feel personal. Side-tie bikini bottoms sit right at the center of that shift. You can see it everywhere. Resort runways leaned into handcrafted touches, vintage-inspired prints, and pieces that looked collected rather than curated. At the same time, celebrity vacation photos have become less about matching sets and more about individuality. The side-tie bikini bottom delivers exactly that. It moves with you. It adjusts to you. It feels effortless in a way fixed silhouettes often don’t. The trick is leaning into the attitude. Wear a side-tie bottom high on the hips with an oversized white shirt tossed over your shoulders and chunky gold jewelry catching the sunlight. Think late-afternoon drinks overlooking the water rather than a perfectly staged beach photo. That’s where this trend feels strongest. I’ve had my eye on AFRM‘s swim collection because it understands that swimwear should be memorable. The Cali Tie Bikini Bottom – Green Snake taps into fashion’s renewed obsession with animal-inspired prints while keeping the silhouette clean and modern. It’s the kind of piece that does all the talking. For something brighter, the Cali Tie Bikini Bottom – Sun Micro Dot captures the optimistic color story dominating Spring 2026. The cheerful yellow shade feels like sunshine bottled into swimwear. I’d pair it with a striped button-down and worn-in leather sandals for a beach-to-town look that doesn’t try too hard. If you’re after a little more coverage, AFRM’s Sadie Tie Bikini Bottom – Sun Micro Dot and Sadie Tie Bikini Bottom – Green Snake prove that fuller silhouettes can still feel fashion-forward. The double-looped side ties give them a distinctive finish that stands out without screaming for attention. The standout for me, though, is the Cali Beaded Bikini Bottom – Sunlight Tile. Those beaded side details feel perfectly timed for a season obsessed with handcrafted embellishment and travel-inspired styling. It’s a small detail, but that’s often what separates a good swimsuit from one you remember. This edit also features Mikoh Swimwear, a label that continues to attract fashion insiders who prefer understated luxury over obvious trends. It’s the brand equivalent of knowing the best beach before everyone else does. My advice? Skip swimwear that feels overly technical or overly precious. Right now, the most interesting pieces are the ones that feel spontaneous. A side-tie bikini bottom gives you freedom to style it your way—and that’s exactly why it matters.
