Too-skinny models misrepresent the "real" human form and cause skewered perceptions in young girls. This can lead to anorexia and bulimia, both life-threatening conditions. It's time for fashionistas to hire "real" girls for their shoots instead of twiggy 6-1, 120 pound freaks who starve themselves on one orange per day just to maintain one of the unhealthiest looks in the world. Who wants to look like someone starved for attention? The self esteem of these models has been shot to hell, and it trickles down to real-life women and teenage girls who get skewered perceptions of what "real" beauty is.
This is like saying "are bodybuilders too big?" Now that sounds crazy, doesn't it? Young girls don't need to see models if it "causes" eating disorders, which it doesn't. This is literally the most unintelligent idea ever. People should know better, than to think the 1% of women that 'professionally starve' to stay skinny for modeling is 'true beauty'.
I don't think that models are too skinny. In general models are meant to uphold a physique that is meant to inspire other girls to look good. There is a perception that models are too skinny, but I believe that some have a structure that other people may perceive as skinny.
