A low-back one-piece swimsuit is one of those classic silhouettes that cues confidence. It’s unfussy but has just the right amount of visual impact — and this season’s best versions come with trend-forward updates that make the staple feel fresh again. From sculptural hardware and subtle metallics to Hunza G-inspired crinkle textures, these suits add interest without sacrificing ease.
Retro references are also making waves: high halter necklines, gingham prints, and dainty florals deliver charm, while tile and toile motifs bring that coveted European summer energy. Even mariner stripes are getting reimagined with a modern, fisherman-inspired twist that feels more sea-swept chic than preppy throwback.
Whether you’re scooping one up from Anthropologie, Free People, Nordstrom, or Zara, this season’s low-back one-pieces strike the ideal balance between functional and cool. They stay put when you dive in, but still give you that breezy, back-baring drama. Basically? They’re the swimsuits you’ll want to wear on repeat. Ahead, our favorite styles.
