THE TANKINI THAT WORKS FOR YOU, NOT AGAINST YOU

A two-piece that genuinely solves the problems of most swimwear. The built-in shelf bra with removable padded cups removes the need for a separate top, while tummy-control boyshorts provide a smooth, confident silhouette whether you're in the water or reclining on the beach. Braided elastic straps sit secure all day, and the coverage levels mean you can move freely without constant adjustment. Nine prints, six sizes — made to be the only swimwear set you reach for all summer.

WHY WOMEN LOVE IT

  • Built-In Shelf Bra with Removable Cups: Integrated support means you never have to coordinate a separate swimsuit top — the cups are removable for a customised level of coverage and shape that works exactly as you want it to.
  • Tummy-Control Boyshorts: The fitted boyshort cut provides a smoothing, secure fit without restriction, keeping everything in place whether you're swimming, walking the beach, or sitting poolside — practical coverage with a flattering silhouette.
  • Braided Elastic Straps: Adjustable braided straps distribute weight evenly across the shoulders and hold their shape and position throughout the day, so the fit you put on in the morning is the same fit you have by afternoon.
  • Modest, Versatile Coverage: Designed to sit at the waist and provide comfortable coverage that's appropriate for beach, pool, or holiday — the kind of swimwear that works in any setting without compromising your confidence or your style.
  • Nine Bold Prints: From tropical palm prints and fresh florals to classic navy geometric and earthy camo — a wide palette of prints means there's a Waveside Tankini for every mood and every summer occasion.
