    Great buy on sale!

    It fits fine even though I opted for the XL+ since the XL was sold out. Beautiful material.

    Flattering bathing suit for petit bust.

    I purchase Sea Lily in size S+. For reference, I am 5'1 and 110lbs with an athletic build. This size fits my body well and I have a petit bust (very flattering). I am recommend this one piece suit!

    Gorgeous!

    THANK YOU for the long torso options Knix! Please please keep them coming. This suit is gorgeous, so flattering and the long torso option fits perfectly on me, I may never buy a suit anywhere else again! The neckline is super flattering and also as a breastfeeding mom, it’s possible to slide it to the side to nurse. The fit is perfect and I really hope they continue with this sizing and offer it in more styles. I find it fits maybe not a tight as the same size I have in regular torso but that could be because of how it fits with the extra length. I’m 6’ tall and typically a L in Knix (sometimes XL in apparel) - the L fits very well.

    attractive suit!

    This suit's V neck design looks great! I wasn't sure if I would like the design, and I definitely do! The suit has good coverage and fits well. I especially like the adjustable straps

    Great suit for long torsos!

    Being plus sized and having a long torso made it impossible to find a one piece that fit and was comfortable. This suit is a nice material and fits well! I like the removable pads for the chest and it feels like great quality. Having the leakproof feature is an added bonus!

    This swimsuit is absolutely perfect for me.! A long torso swimsuit is so difficult to find. It fits so well . Love the deep v neck and the softness of the fabric. I am very happy with it . Please make other colours 😊
