  • Great suit!
  • I love this suit! I'm so happy I bought it. It's super cute, very figure flattering, is easy to put on, is comfortable, and I like the option of wearing it with or without the halter top strap. My only complaint is the band is not adjustable and is too loose. I'm a 34F and got the 34F suit, and everything fits great except the band around the rib cage. Because it is too loose, I feel like I have less support and have to rely more on the optional halter strap, which is not designed to be the primary support mechanism. It doesn't make sense to make a bathing suit in bra sizes and then not have an adjustable band like a bra. If only it had that feature, I would definitely give this 5 stars.

  • Adorable tankini top.
  • I purchased this top because I needed a tankini with straps, so I could pull one side down to nurse my baby. This suit fit the bill and was also very cute. I appreciate it's lift and smoothing, but note it's very structural in nature to get that effect - the underwire is fairly constricting and it's a real pain to wrestle on and off.

  • Great fit!!
  • I bought this top from another site for a very reduced price and it is excellent!! Mine is red. I ordered a 34G hoping I could finally find a swim top that held me up without spilling over and that didn't give me a literal pain in my neck (I hate halters!). There is a bra closure in the back too for extra support. The only slightly negative thing is that the inside liner goes all the way down, so when swimming the top layer floats up and reveals the inside layer. Otherwise, this is a must have if you like being active in the water and not exposing all your bits!!

  • Bra Like Fit and Great Support for Larger Sizes
  • Aside from wonderful customer service, this top is the best bikini top I've ever owned. I am a 34DD typically but bought the 34E. Also petite so the top ties adjust nicely. My suggestion would be to purchase your normal band size but consider buying a cup size larger. You will be fully covered. It has a plastic line around the bottom to prevent slippage and the cups are more molded than padded so it hold up in water. This is a great bra for larger cup sizes.

  • Simple shape but great support
  • I was looking for a one-piece to swim in at the pool and have tried way too many before finding one that hold my chest in place while letting me breathe at the same time... This one was the answer. The design is simple yet elegant and the fringe on the side make it very feminine. The design is well thought out and very comfortable; the material is rather thick and stays in place.

  • Loved it but returning
  • I loved this top and it fit well and looked great with the exception that I'm not comfortable in a two piece. Would love to see this top built into a one piece that has an attached skirt. Why can't swim suit designers design suits for people over 40!? They only think of young women when designing!
