I wanted something to compare with OnGossamer Hip-G thongs, but for a much better price and these looked like they might do the trick. I am quite small, wearing a size 0-2 in pants, but after reading reviews from others about the sizing, I opted for the Medium size. While not uncomfortable, they are definately small! Even at my size, I could have probably gone with a Large! The quality seems good, but the sizing is WAY off! The elastic bands are very stretchy, which makes them comfortable enough, but they still cut into your skin making a slight V.P.L., which seems to contradict the exact reason we wear thongs instead of panties! They have not gone through the wash yet, but I am definately going to air dry them to reduce the risk of them becoming any smaller! If you are relatively small, order them in a Large, and they will probably be just fine! If you regularly wear a size Medium or a Large, you might want to avoid these!
