How Do Models Look So Great ?

I  done a bit of modeling for youngers but is what i did to get thin (not to thin) instead eat only chclate and things because its putting fat into you but your not eating others so you have a good body also for alot of people comes natural being thin also  its because there faces are sametrical(nearly same perfect both eyes look so same) and a foundation no spots make-up blusher and depends the way its put on also we keep our backs straight!
