Ugh, I hate that I have to dress for protection on occasion, whether it's an option or not. :/ But that is a different discussion!
I understand than men have markers too, but they don't have gender markers, so that's one less category for them to worry about than women imho. For instance, no one will assume a man is a prude based on his outfit. They might assume he's poor, or not intelligent, but they can assume that about a woman too. I do find the idea that men's clothing is more about displaying wealth & status interesting. I wonder if this has to do with career fields, because I imagine high flying women executives and lawyers would need to show the same attention to quality and ability to pay for it. No? But those are fields traditionally associated with men. None of my good guy friends are in such professions, so they definitely don't have the closet dilemmas some of you have described. Society is so fascinating! I just finished reading Luella's Guide to British Style, which had a long chapter on class and dressing, which was essentially an exploration of such markers (on both men and women). It made for an interesting, thought-provoking read, although of course the book was written with a light touch.
Suz also makes an excellent point about women becoming less 'marked' as time moves on, and they become more visible in certain fields. I love that there is now a female academic uniform where she lives! Having read Academichic, and being a bit of a bookworm myself, I'm always curious about where style and academia/intellectual pursuits collide.
Also, it is a shame that men can't experiment as much! We should all overturn patriarchy together, so that men don't have to be in their tiny 'man box' anymore (I got this concept from a male feminist who's written a couple good books, but his name isn't springing to mind right now).
And I loved Diana's science stuff! I read a really neat book about the X chromosome once (with the unfortunate title of The X in Sex) that made me appreciate calico cats in a whole new light.
