Bought these for my girlfriend and the material is amazing. like a super thin spandex material. I thought the thing was made out of a napkin or something when they arrived because they're so thin. But good Lorrrrd. they make good looking curves even better. She claims they super comfy. So to sum it up, they're "comfy" they are very very attractive(coming from a dude) and they're Calvin Klein so they'll be here for a while. Good stuff!
