I bought a pack of Hipster underwear for women size 6. Based on the size chart on the back of the package I should have bought a size 5 but I decided to get a size bigger to be comfortable, but size 6 is too tight and cuts into my skin! I am a size 6 dress and 36' hips so according to the package I should fit into a size 5 but size 6 was even too small. I recommend you change the size chart! And maybe size 7 shouldn't be labeled as Large because I'm not large (5'7 125 lbs) and now I have to go buy a pair of LARGE underwear!
