Looking sexy for someone has nothing to do with pretending to be someone else! It makes the other person know you're interested, or it can make it special. I dress sexy when I go out with my boyfriend, and yet I act exactly myself when I'm with him. If I were to go out on a date in torn jeans it means I don;t put any effort into the relationship and couldnt care less what he thinks! If a girl goes out and buys lingerie for a guy, is she pretending to be a hooker? NO she's probably just going to surprise him for some fun in the bedroom.
