These are really meant for someone who is completely shaven or waxed and they are a little tight on me. I wear size 13 (juniors sizes) pants and if I was any bigger they wouldn't fit. Definitely not for those with big butts like me haha. Since I can't imagine wearing them more than a couple of hours they'll be okay and I'm sure my boyfriend will think they're very sexy. As far as the material goes, it's a little scratchy, but not too terrible. They were cheap so I got what I paid for.
