Okay so if you’re like me and you look at a ton of reviews before you buy something this is a good review for you. I’ve had this product before but in a medium and I lost it at a hotel I stayed at. In the medium I quickly moved to the last clasp and felt I needed to go smaller. This time I bought a small I received it today and im liking the way it fits. I’ve always been in the 150-160 lb range and I’m 5’5. Also the medium was a little bit longer and was noticeable on some outfits I wore it under. This is not meant to permanently change your body shape for that you have to go to the gym. This is a temporary fix and can assist you in the gym, I use it on cardio days and sometimes legs. Please be careful if you use this at the gym because it makes you sweat in one area profusely! And the sweat stays within the trainer like a nasty soup lol. I’ve included pictures in my gym clothes and in a regular skin tight dress for people who’d like to see both!
