How to measure yourself

  • Bust — measure around the fullest part, wearing an unpadded bra.
  • Waist — measure around the narrowest part, just above the navel.
  • Hips — measure around the widest part, standing with your feet together.

Torn between two sizes?

Our seamless knit shapes through its structure, not through tightness. Between two sizes, always take the larger one — a size too small leaves marks and rolls at the waist. For a stronger sculpting effect, choose a firm-control style instead.

Description

This low back one-piece swimsuit shows off your back while keeping your bust and tummy fully supported — the kind of suit you wear when you want to be seen.

It's lined and seamless, with a deep V-shaped open back. The front is full coverage, with a built-in tummy control panel that smooths your midsection, while the barely-there back keeps it modern.

Most open-back swimsuits sacrifice support. This one adds a discreet elastic band under the bust and pre-formed cups, so you stay supported without straps across your back.

Wear it at the beach, at the pool, on a cruise or for drinks by the water.

The appeal of an open back

It's all about contrast: modest in front, dramatic behind. A plunging V-neck up front, and a deep scoop in back down to the small of your back. Support comes from the structured bust and thin halter straps, so nothing needs to cross your back. Eye-catching, without going over the top.

Which swimsuit back is right for you?

Back styleBust supportHow boldBest for
Plunging V low back (this one)Good (structured bust + halter)HighCocktails, photos, hotel pools
Closed backBestLow-keySwimming laps, family beach days
Crossback / racerbackVery goodModerateActive swimming
Deep '90s scoopLightVery highTanning, statement looks

The plunging V low back is the best balance between the wow factor of an open back and real support — something very low '90s-style backs often give up.

Where it shines

  • Beach weddings and waterfront events — stunning under a sheer cover-up or kaftan.
  • Vacation photos — as photogenic from behind as from the front.
  • Hotel pools and rooftops — a polished look for places you want to be seen.
  • Fewer tan lines — no straps across your back.

Support, even with an open back

A structured bust with built-in support and adjustable halter straps share the work, so the V-neck stays in place without gaping and the thick seamless fabric smooths your front. For D cups and up, tighten the halter straps for the best hold. Sizes XXS to 2XL.
