Love it gives support and covers the back fat! True to fit





I'm a 34-36 DD-ish and the X was about perfect. It's definitely a bit pre-shaped (but not pointy), and sits a little narrow (squishes from the sides a bit), but totally fixable with a little stitching to tighten up the back. When delivered, the straps were at maximum tightness -- make sure these are loose before you 'get in' unless you want cleavage at your chin. Otherwise it seems well made and sturdy. Not quite structured enough to go strapless, though.

Fantastic top!!


I'm a busty girl and have a hard time finding a bathing suit top that offers coverage, support, and comfort. I love the wide band. It gives my waist a slimmer look. I feel comfortable wearing it without the straps and feel like I'm not going to fall out. Pairing it with high waisted bottoms gives it a retro and subtly sexy look. I absolutely love it!
