I hate the fact that Tyra coined that every model needs neck in a photo!! They Dont!! The only time she let go of that criteria was when she let whitney win the no neck monster!
An elongated neck adds elegance to a picture. It has nothing to do with what Tyra Banks says. It creates a much more interesting line. It's not like ANTM started the craze for long and elegant necks, it's just a staple look.
