because that's how other women will be dressing at the club and so she wants to be as hot or hotter than them. it boosts a girls self esteem when they can look better. and at clubs that's just how it seems you're supposed to dress no matter who you're going with. if it bothers you, casually ask her yourself. its not like she'll freak out because you ask. just say "you always dress so sexy when you go to the clubs. why?" if she wants to know why you're asking just say I don't know I've just noticed it... good luck.
