Clothes mold to the shape of an avatar?

In my game, players can design their characters using sliders to change their characters body shape and facial shape, if you’ve ever played The Sims 4, it’s similar to that. How can I make it so that clothing items can fit to the shape of the character? I’m using unity 5.2, until i can get a new computer (not soon sigh)

Basically, you need to apply the same logic you use to change body shapes to the clothing. But even then, it’s more about art direction than logic. Without the right art direction, the clothing will clip like crazy.

Check out UMA from the asset store (free). A great starting point when thinking about a character customizer.
