Well i think she is anorexic And this is just a sad comment on a problem she is suffering from and need s help .
But if you look at some of the physiques through the centuries There were a number of time in different cultures where very thin waists were made desired .
Back in the thirties and forties .. Look at some of the waists on the movies starts and dancers .. There were a few that were as thin as that .. it was not pretty .
I like thin and small breasts but only when it suits the person and they are not starving them selves .. an extra thin waist and big hips or boobs like Jessica rabbit does not do it for me ..
