    My new favourite one piece!

    Wow this swimsuit is SO flattering. I am larger on the bottom than on the top and have a slightly fuller breast for my frame. My hips measure 38”, waist 25”, and my bra size is 30DD. After reviewing their size chart and all reviews I decided to size up in the cup. I ordered the XS+ (same size I would be in Knix bras) and am so glad I did. The hips dig in a little bit I know once I wear it a couple times that will resolve. The cups fit much smaller than the size guide suggests so if you're at the upper end of the guide get the +. I can't see how this would fit someone with much more than a cup size above me; Knix needs to make ++ swim sizes for the F and Gs. I feel so confident in this bathing suit! It pushes the girls together and provides nice cleavage but I still feel covered enough to not be so self aware around family, which is what I was looking for in this purchase. Can't comment on longevity yet as I haven't worn it in water. So far so good.

    Great buy on sale!

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

    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.
