I usually wear size medium but I bought small. I forced into this one week post partum and i was  so happy with the perfect curves i had! it was very tight but i didn't keep it on too long each time and it was just what  i needed to help get  my  shape back. this worked great and i received  many compliments but the hooks are wayyy too weak and the reason i am GIVING THE PRODUCT 3 STARS. the hooks fell apart one  by one and after few months it was tossed. I wouldnt buy the ones with hooks again
