Bye Bye waist

Ok, so Im a pretty thick girl. I wear a size 10-12 & THIS is how this fits me & this is a small. I ordered a small on purpose because I’m steady losing weight & I wanted to get a waist trainer that can go with me. I wear it on the first row but still have 3 other rows to go! I like the fact that it’s stretchy and really thin. It Can for sure be worn under your clothes as a girdle. It was delivered fast!! I will for sure recommend this product.

Amazing! Third time purchasing this trainer

This is my third time purchasing this waist trainer. This waist trainer has been amazing during my weight loss journey. I started off with a 2xl, and just purchased small. Comfortable and great for portion control. No more Fupa over here!


This is perfect , I got the Xl and it’s the right size. I followed the sizing chart. I’m able to move around and not be uncomfortable. The customer service is amazing. I went through the reviews before purchasing I just wanted to make sure I got the perfect fit. I’ve been using it for about a week. I’m on the first strip , exciting to be on the 2nd one !!! The fabric is very COMFORTABLE !!!! something I love because other material is itching or just not right. Really recommend this product !

Snug and comfortable

Great value for the money. I'm between 135 & 140, so I got the medium. The first row of hook eyes fits, the second row is snug, the 3rd row will stop your breathing, but your waistline will be snatched while you're breathless.

Fits great

This waist trainer fits great and is undetectable under clothes.
