I like to see girls with braces, but I don't really link it to young girls...Maybe because I didn't know a lot of girls with braces as a kid (or if I did, they didn't smile or show them off a lot...go figure)...I think mostly it's the "Girl+Metal" and perceived "danger" about it all that I enjoy. lol Plus, it's just different looking, I guess, which can make it seem exotic...*shrugs*
Also, I didn't know anyone called suspenders "braces"...>_>
