What do you mean? Do you mean why make them? I made them for people that role play in minecraft. Or do you mean how come so many colors/choices? I make choices of outfits and hair colors for most all my skins...if you look at them all you will see that. Also, I make my skins mostly for girls, and girls like choices. They also like to change colors of outfits and hair more than guys usually do. :)
