    • 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!

    • 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.

    • 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!

    • Love this suit, however, I ordered based on previous Freya Purchases and it was a little big in the chest. I would order one cup size smaller if I was to do it all over. I am 5'4 and sized at an E Cup and was worried about the length of the suit on me and it was perfect. Very slimming and I got a lot of compliments.

    • The suit Is quite complimentary of my body shape (large bust) and looks lovely while wearing it (both dry and wet). It's a bit difficult to put on due to the way the built in bra/cups made but comfortable once it's on.
