    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

    Love it

    As a taller person I love the long torso option for an actual flattering one piece!

    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!

    I love it

    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 😊

    Love the fit - NEED more colours

    4/5 stars because Knix has not provided more options in this much-needed style! Long torso babes are some of the hardest people to buy one piece suits for and being limited to only one colour is deeply disappointing. It's a great suit, and I would totally own multiples if I were given a choice of colours and patterns.

    Love the length, fits my longer torso well without it pulling or the straps feeling too tight. Need more colours so I can buy more!

    Fits great, doesn't last

    I bought this swimsuit in the blue colour and wore one time in the banff hotspring. I rinsed in cold water afterwards, wrung it out, put it in a bag, and rinsed it in more cold water as soon as I got home. The dye of it faded into a weird, yellowish grey line up the bum, making a T on the front across your crotch, and then an additional faded line under the boobs. If I wear it now, it looks like I've got some sort of weird sweat/funky situation happening. Really disappointed as the fit was so flattering and it holds you in really well. Not sure if black would do the same, but if it did it would be even more noticeable of a contrast :( way too costly for one wear

    This suit is amazing! Flattering, full coverage, comfortable, and confidence-inducing. I have never put on a one piece I enjoyed so I think the length for the torso and lower thigh cut is key for me (half way to a retro cut). My only wish is that the back opening was a little deeper, almost too modest but still so lovely!

    It's ok

    I'm 5'11", 36DD, 180lbs, post partum. I've tried the regular L, long torso L,XL & L+. I'm going to keep the L long torso. The leg cut is very, horribly unflattering. it cuts in so much around the thighs & bum. But XL is baggy everywhere else. It's just not a nice cut around the bum and thighs - old skool; 1960's cut. Haven't used it for the function of how well it would ensure zero leakage. It is nice to have though. Now I don't have to plan my whole life around my period. So it's nice and liberating from that perspective

    Amazing!!!

    Most comfortable one piece I have ever owned. Does not pull in the torso. Please keep making stylish one piece suits that have a long torso!!

    So comfortable for a long torso!

    This is a great swim suit. Support is great. I wish there was also a zero leak proof option, because it does hold water more than usual so if you don’t need it for leakproof, it’s a bit overkill. But happy this fits my body!
