Oh, and just a thought:

I live in a small community (100 people) of graduate students from many countries. We take all of our meals together and share a number of common rooms.

Not so long ago, Japanese Woman X is sitting in the dining hall with her legs crossed. Japanese Man Y, a relatively friendly acquaintance but by no means a close friend, walked to her, slapped her on the knee and said (in Japanese, so I rely on her for the translation) that this was not a proper way to sit for a Japanese woman. There is no reason to believe that it was a joke.

She didn't feel too good about that, to say the least. I can't even start imagining the conflicted feelings she must have had following that event. It made ME very mad. But I'm sure her own feelings were much more complicated...

So generally I think it's safe to assume that how women dress, eat, sit, look, act, etc. is not just about their own "choice"... The same probably applies for men, as all men who have been found to be "too feminine" know...
