You must be foolish if you think that style doesn’t matter. When a girl first sees you, she tries to guess if the two of you would match on a picture, or in front of her friends, family, co-workers, people. There’s only two options : YES, and NO. And NO (unless you are veeeery good) means game-over. If she cares about her style, you’d better care about yours. Hey, Cary Grant and James Bond didn’t wear flip-flops !
