  • My favorite bikini top ever!
  • I bought this to go on my honeymoon to Costa Rica, with the thought that I would be wearing it all day like a bra but would also be able to go snorkeling, lounging on the beach, and swimming in it. This top did not disappoint. It was JUST as comfortable as my prima donna bras and provided the same GREAT support, but it actually looked like a bikini. So many of these just look like bras and this one didn't I LOVED it! FYI - I typically wear a 30G in the prima donna bras and had to upsize for this, I originally ordered the 32F as recommended by bare necessities, but the cup was too small, but I reordered and the 32G fit PERFECT! Order this - you wont regret it!

  • I have such a hard time buying cute swimsuits because I'm not that big- typically an 8 or 10, but a 34FF. Bare Necessities customer service has been amazing while helping me find the right fit that looks good and has support. I got the matching bottoms and the hot pink bottom too. Super cute, fashionable and great quality. Off to the beach in Barbados and will feel so good with all kinds of new bathing suits!

  • Patricia 55yrs young
  • I absolutely love this swim top! Very supportive & classy looking. I ordered a different top from pour moi, although beautiful, not as well made& didn’t look as good on. I’ve recently lost 25lb and want to try a bikini for the first time since my teens, mostly to wear when boating. I am a 32G, but the Uk equivalent was a 32F. The top fits well, although since I’ve lost weight, I’ve lost a bit of volume in my breasts and if I loose more, I may need to add a pad to take up any gap. I will review the fold over bottoms separately.
