I don't think this is fair at all. You can have your opinions, but they have the right to wear what they want and what's comfortable. They don't need to make themselves uncomfortable just to please other people that don't matter. Being judgmental is uglier than having physical imperfections.
I live in jeans and sweatshirts in the winter and go all out with switching to T-shirts in the summer. I haven't worn shorts for 30 years now, my legs are too knobby and full of spider veins. When I see all the women who SHOULDN'T be wearing shorts, I'm glad I wear jeans. They always say, I don't care I want to be comfortable, but they sure make the rest of us sick to our stomachs! PLEASE, not in public!
