Introduction

The tankini is the ultimate compromise between a bikini and a one-piece — offering the easy bathroom breaks of a two-piece with the coverage of a tank top. For plus-size women, a well-constructed tankini can flatter the waist, support the bust, and keep everything in place during active water play. Here are our top picks for stylish and functional plus-size tankinis.

What to Look for in a Plus Size Tankini

  • Fit & Cut: A tankini top that hits at or just below the hip provides the most coverage. Empire waist and ruched styles draw the eye upward and minimize the midsection.
  • Fabric: Opt for a sturdy, quick-drying fabric with at least 20% spandex. Look for fabrics with built-in UPF protection if you spend long hours in the sun.
  • Style Options: Mix-and-match sets let you size the top and bottom independently — a huge advantage for curvy figures where a size medium top might pair with a size XL bottom.
