Why do we wear Clothes?

I'm sure there's people you'd like to see naked, but than theres many you don't. Just think of it this way, You're eating at a restaurant and you see a big hairy man or lady sitting at a table chowing down. Would you really want to eat anymore? Or some sweaty person that has moles all over their body. Or I could go on and on and on. But I think that's enough, you get the scene!
