    • This top works!
    • I bought this top for an upcoming beach vacation. I love the way it covers imperfections, such as a belly and bulges, yet still looks sexy. I wish more tankinis were made like this with the longer tail in the back to cover a big booty. Very flattering suit for curvy ladies! The underwire feature gives great support and drapes very nicely.

    • Super flattering and supportive - love it!
    • This is a simple one-piece that holds the girls up well. Maybe not for a jog, but certainly for flitting about at the pool or beach. It's otherwise conservative and very comfortable, but the good chest support makes for good cleavage in a not-overly-sexy-but-not-granny-suit way. I was very comfortable in it and received a lot of compliments.

    • Fits securely like a bra but sexy
    • Bought this top and love how the wider back band fits securely like a bra but still let me feel sexy. I am a D cup but I felt the D was too small and got the DD. In another brand I also purchased the D fit and the DD was a bit over large. I would definitely recommend Pour Moi and I plan to look at their items first for future purchases. The service at Bare necessities was very good as well.

    • I feel so cute in this!
    • Bought this in the hopes of finding a supportive swim top for a 32G. This is a UK sized 32F, I'm not sure if that size is actually equivalent in the US but it works for me! The only possible complaint I could have is a little bit of spillage at the cleavage, I'm not used to that but it gave me the opportunity to look like a hot mama at the beach! I love this swim top, it's adorable and fits everywhere else nicely, the straps are solid and I actually feel supported! Thank God! Finally a swim top that works!

    • Full support, good coverage
    • This swim top provides bra-style support and full coverage. While I like the one I have, I feel that I could have bought a cup size smaller to get less coverage and more of a sexy look. I'm in between cup sizes, so if you are too, you might want to pick the smaller cup size unless you are going for the full coverage. Even with all that coverage, the top still looks good. The straps are adjustable. There is no padding in the cups, which I love because I already have lots of "built-in padding."

    • I bought this swimsuit and a tanikini before a trip to the beach. This is the first one piece swimsuit that I have been able to find that provided enough support in the chest. The underwire is non-intrusive, but provides ample support. I love this swimsuit!
