I honestly thought we'd exhausted this topic, but no, more ideas keep on coming!
JAileen, Deb, thanks for the sports shots. I've noticed similar trends in soccer. (I kind of like the tiny shorts, they make me feel nostalgic). It's a really interesting observation, particularly considering the way that translates to urban sportswear.
I'm intrigued by menswear=loose/long vs womenswear=short/tight, alongside the American feminist narrative around showing one's body. I did a quick and completely unscientific study of styles on lookbook.nu, and there does appear to be a trend among users on the West Coast towards more revealing and bodycon styles, which you're less likely to see in Europe.
Another thing: we were talking here in IRL about the idea that looser clothing might suggest that a woman had "let herself go" as it were, which goes against current ideas about body positivity and empowerment. This is also part of my own internal narrative, maybe a reason for my feeling a little sheepish about posting these looks here. They feel to me quite relaxed and effortless, but to another eye that might translate as just plain lazy.
