Ewww Gross Nudity?

Maybe I'm just weird but I'm not offended by nudity. Also, can you define to me what a slutty outfit is? For some reason, plenty of the outfits I find cute are considered slutty. Also, why is a girl considered a slut based on what she wears? How would you even know if she sleeps around? Just because she wears a miniskirt does not mean she can't keep her legs closed. I don't get it.
