Why are females so interested when you have a certain dress style?

Ok, so im just curious to why Females seem to give me more attention when i have a certain fit on(clothes) and Hair style. for the night. And when im wearing regular bummy clothes, or plain tee's and jeans. I get no play? why is that. Not be rude or start an argument but, i mean i have no problem with it. But it seems most females are superficial/judgmental? Ive grown use too, And yeah i know most would say not all females i know thats tru, but still why is that? lol i just think its kinda funny cause its like an almost step by step process to pull a certain type of female just by your apperance. WHY IS THAT?
