    Super comfy

    Never wear a one piece because I feel like they make me look like a toddler, but I feel pretty good in this one piece. I just had a baby this past year and needed a one piece that my boobs don’t pop out of. This is it. It’s comfy and covers my bits. I feel good. I bought my underwear size and would say that I should have gone down a size. It fits but I wouldn’t mind if it was a little snugger on my bits.

    Swimsuit

    I purchased the sculpt swimsuit in the summer and I loved the structure. This one is not as supportive. Still a nice color and fit in the busy area. I wish the cut on the bottom was more full.

    Swimsuits review

    The swimsuit itself is great but it is cut a bit shorter than the last one I ordered.

    Love it!

    It’s comfortable and stylish..

    It’s a double layer so it does take a bit longer to dry!

    I love this swimsuit, I've bought it several times now. I just find the chemicals in the pool make it wear out quickly.

    Favourite Suit

    I love the suit so much! I own it in two colours.

    It’s a super flattering fit while being extremely supportive and comfortable. I absolutely love that. They make a size small with large larger cups! I’ve never had a suit that fit so well.

    My only complaint about this colour is that the liner sometimes creates weird lines/strange looking, pleading in the crotch area.

    Still the best suit I’ve ever had!
