    • Opinion
    • I have a smaller frame with large breasts and it's made it very difficult for me to find a swim top that I feel comfortable in and that holds me up. I'm 38 and I finally feel like I have found one! There are some things that I would change, and that is that it's a little see through, but I have that problem a lot. Overall I am very satisfied. Customer service was very friendly and seemed concerned about any issues I had with exchanging or returning.

    • Perfect balance of support and tummy camouflage!
    • My bra size is 36DDD, but this still worked for me. Adequate support and adjustable straps make it feel like wearing a comfortable bra. The loose fabric around my middle makes me feel unselfconscious walking around in this suit. Highly recommend!

    • Gorgeous, Vibrant, Comfy
    • Really, the title of this review says it all... this tankini is so pretty & is overall flattering, as it is not at all clingy, but is still attractive. Love it with any plain color bottom you would choose- black, magenta, purple- they all would look great. Bare Necessities had this tankini top at a great price, plus an added discount. I preferred the size 12 over the 10, only because the bust had a bit more coverage. Well made too!

    • Finally - a swim top as comfortable and supportive as a bra!
    • I've spent my life with my chest rammed into supposedly bra-sized swim tops (only up to DD sizing, of course) or overflowing shelf bras. Now I finally have a swim top as comfortable as a bra. Life changing!

    • Lovely suit -- only one flaw
    • This suit is downright beautiful in front -- accommodated my D cups with no effort, something I've never seen in a fashion suit before. Unfortunately, the back of the suit did not lie flat against the small of my back (the fabric went straight up vertically from the bum), a weird error that I've *also* never seen before. It added thickness to my figure from either side, so I had to return it. Really hope to find a similar suit next year without this odd flaw (which another commenter mentioned in a review of a similar suit by this brand).

    • The band size runs small, so I ordered a size up after checking other reviews. The support is great and the fit is nice. It covers up any side boob, if that's a concern. So overall this top was a real win.

    • Wow!
    • I would've never found - nor chosen - this bikini myself! I ended up using the on-line for specialists because I wanted a new bikini for vacation and was having trouble deciding on a size in a different one. She steered me toward several other choices and assured me this would have the support I was looking for. She was right on the money! I love the navy with white and it's a very cute style AND feels supportive!
