They are skinny to the bones yes, as all models are, but look at their facial expressions. Some have that expression like she's going to tear the carcass of some poor beast apart and eat it whole as soon as the show is over. Some look as though they'll attack you and eat you!
pissed off for having to parade around in such a stupid getup that no self respecting woman would be caught dead wearing on the street. I mean, WTF!!! Have these designers gone fucking insane?!! Are they off their meds?!! That could be the reason for the mean nasty looks the audience and cameras get from these poor girls. They just want to vent by beating some poor unfortunate designer into a bloody pulp for no reason at all.
Hmmmmm... just a thought.
