I know a couple of girls who wear fake glasses when they are camming. They look like regular glasses but the lenses are clear. They both seem to do well with this quirky image, so if you are looking for a way to switch things up a bit it may be worth a try.
We saw quite a few girls who seemed to be wearing those when we visited the red light district in Amsterdam. It definitely adds a sexy something to a woman, though I’m not sure it works as well for guys.
Sounds to me like these girls are trying to play the “sexy school teacher” angle, or maybe the “sexy librarian”, ha ha! “Lucky” for me, I have to wear real glasses, so I get to play that angle everyday unless I wear my contacts. 😉
