      ****** me up!!

      Oh yeah, this waist trainer is snatching me!! It's a definite complement piece to my regime. I’m starting to see more definition after wearing a month. I love the feel & the quality is so well made. I thought I purchased the wrong size (hard to zip up at first) because it was super snug zipping that puppy but when I got it on, I just needed to break it in. It seamlessly vanishes under my shirt while giving me the back support during strength training. I’m glad I decided to purchase. It’s SO worth it!!

      Love it

      The height and weight really helped me to choose the correct size. I recommend this product. Also love the fact that the straps can be removed. Cant wait to get to get the next size down! Shipping was also fast. I wish i could give this product 10 star rating

      Love love love!

      The trainer is great! I’m 5’7, 150lbs, and i ordered a medium. It fits great! Small would have been too tight. Glad I ordered a medium. Love my purchase.
