    This body suit is amazing

    Fit perfectly under my dresses, very customizable even under a dress with a very low back.

    Snug Fit

    I really like the dark pink bodysuit. I wore it out as a top and no one knew I had a bodysuit on. But, the torso is too long. I'm 5'4 and 135 lbs, wearing a size 4 pant. And I had to jump into the medium to get it over my thighs. But, the fabric bunches around my crotch bc it's too long for me. With high-waisted pants, the bunching is barely visible, but not ideal. An option for shorter ladies would be better. I do also like the crotch clasp to open/close to go pee. It's super easy to open and close.

    No give, not true to size. If you have thick thighs, no getting this shapewear on.

    Highly disappointed with this shapewear as I love the Knix brand and always thought the fabric was so comfortable and flattering. There is no give to this shapewear. I tried multiple sizes that are my true size and I could barely get it over my thighs. It’s soft fabric with good support, but very little stretch in the rib region which made it impossible to get on. Was really looking forward to using the custom shapewear for a low back bridesmaid dress, but apparently I’d need to seriously size up for this to work.

    Does NOT fit :'(

    I bought a size M+ because these are my exact dimensions. I am so incredibly disappointed with this garment because I can't even get it on. I tried stepping into it and putting it on over my head and there's so little give that I can't get it over my chest or hips... The sizing discrepancy of this garment is bringing up all kinds of old body shaming thoughts. And now with their return policy, I get a store credit and have to find a new home for it. What a waste.

    The most comfortable Bodysuit

    The material holds wonderfully, it’s breathable and the hooks are way easier to use than any other bodysuit iv owned. Having the option to customize the back is so ideal.

    The compression is good but the bust liner inserts don't sit well within the cup due to the high level of compression right under the bust line. I usually have no issues with Knix fit but this one was a little off. Maybe could do with a less compression directly under the bust line.

    Thong Bodysuit

    One of the best bodysuits you can wear. Extremely comfortable, did not rise or bunch. Highly recommended.
