How tan-through works

See-through? only to the sun.

  • Lets the sun throughTiny openings in the knit let UV reach your skin, so your tan carries on under the suit.
  • Covered when it’s onStretched over the body, the weave reads as solid colour.
“They may look see through when they aren’t on but trust me you see nothing when they are on.”Nellena · Verified buyer · Kastani Top

UV passes through the fabric, so wear SPF underneath, just as you would on bare skin.

The glow is real.

XL–3XL fit so comfortably

“This truly is one size fits all (or a couple sizes fits all). I'm a 14/16 in pants or a true XL for tops and the XL-3XL size fit me so comfortably! It's extremely stretchy but not see through. …”

Pleasantly surprised

“I was a little skeptical when I pulled the bikini out of the packaging. It looked too tiny to fit my bum. I was more than pleasantly surprised. It is comfortable, fits well and even hides my apron belly.”
