Why?

Why is it that in fashion every single girl is a stick? Please tell me the answer and don't say "42" . It baffles me because been doing some research and almost every female actor or model in or around the fifties was not a stick! Take Marilyn Monroe for example;  she would now be considered plus-sized! This is just crazy no wonder lots of girls are anorexic!

I lurve you chickies!

XOXO,
