  • Love this, very well made, usually tankinis are baggy in the waist, not this one, hugs nicely without being to tight. I typically wear M\L or 10\12 in general sizing.

  • So comfortable!
  • I ordered this tankini, assuming I would probably have to return it, as nothing ever seems to fit me right (just under 5' and DD), but it looked worth a try. Not only did it fit, it's the most comfortable tankini I have. It fit so well that I ordered another one in a different color. Wish it came in prints as well - I'd order more!
