@MickeyMouse I've noticed since I moved here, in the general public NO single soul is skinny. Even thin is a hit and miss view. There's not a lot of obese people, but you hardly see someone who is rather fit, unless a football player.
Back in the states, you'd think my university was made for models because everyone made it their deal to look skinny, men and women alike. It seems the English like their sweets is all. You don't see a SoulCycle on every corner here either, I'd say walking is the most exercise people do. While that's not bad, it can be rather hard to lose weight from that.
I have never seen Kate as outstandingly skinny, but I'm not sure why. I think part of it has to do with how natural it looks on her. But god that does not matter when you can photograph like she does. And I absolutely agree with you regarding her life. Everyone knows she partied and still does, but they truly find that as a bad thing? They think it's a bad influence, but I think that as long as she's been modeling, she hasn't been a great influence. For the general public, obviously. I mean President Clinton in the nineties made a comment about "heroin chic" and how it should not be idolized.
