best style to pick up girls at dance night clubs?

[HeykidImacomputert]

so for my bit=birthday I went to a night club and loved it. but Idk about my style I went in a holster shirt, jeans and forces which probably makes me come off as a high school kid who has no money. what would be the best style to pick up girls at the club? also what is a good way to ask a girl to dance? I'm kinda shy and everyone looks like they have boyfriends
