Details

Designed for the woman who swears she’s “not a bikini girl.”

Supportive enough for big busts. Flattering for small busts. Comfortable enough to wear all day. And yes - cute enough to turn heads.

The All Day Bikini Top was created for women who usually scroll straight past bikinis. With real support, a clean flattering cut, and wide straps that don’t fall down, this top gives you lift, shape and comfort - without the digging, slipping or awkward adjusting.

WHY YOU'LL LOVE IT:

  • Clever bust sliders so you can fine tune your fit (and your cleavage)
  • Fits A–F cups 
  • Fully adjustable, elasticated straps - wear them straight or crossed
  • Built in bust support for excellent lift (no underwire needed)
  • Made from ultra matte, smooth recycled fabric
  • Clean, confidence friendly neckline
  • Fully lined with no padding or foam cups
  • Luxe gunmetal hardware
  • Chlorine resistant rating - 4/5
  • Flattering cut that shows a subtle peek of side bust
  • Designed to match the All Day Bottoms

Got a bigger bust? Cross the straps for maximum lift, no slips, no neck strain and zero adjusting - even on active beach days.
