True, and I also remind myself that some girls really are made that way. I used to do pageants with a couple of girls who would eat like crazy TRYING to gain weight--most girls who have bodies that slender also have no boobs (unless they've had a little surgical help) or butt... It's really a double edged sword.
Those of you who know me, know that I've gone both ways--thin and thick--and I think that everyone has those pesky self-esteem issues that drive them to distraction. Some of the prettiest girls are, unfortunately, their own harshest critics.
There were some really nice article pieces done for Elle (IIRC?) last year, and I love the Dove Real Beauty campaigns, focused on beauty no matter what the size.
I think all women are beautiful, and really believe that TRUE beauty comes with loving and accepting yourself for exactly who you are. So, before judging them so harshly, remember that they are trying to make a living, and doing what is necessary to make it happen. Just my .02...
