You & I are on the same wavelength Steph.
"And yes, I definitely agree that men created the norms, but if everyone continues to accept the "rules" and play along, nothing will ever change." <<< VERY true.
I can see why women are perhaps a little apprehensive to bend the rules at first, but once you have settled into a job and proven yourself as bright and competent, I don't see why something like long hair or heels or anything else specifically feminine would change that. These are really trivial things, after all. Since this is a style and image forum, I think we get a little overly conscious of appearance and forget that most people may not even notice or care. In the end, it goes without saying that it's less about style and more about substance. Sure people have their preconceived notions, but those are easily disproven and debunked...to Steph's point.
On one hand, we are told we should look our best and present ourselves with pride and style. OTOH, we are told to suppress any last bit of style and individuality. You can't win can you? It's probably a very good thing that I happen to not be in a male-dominated or unusually sexist field. The feminist in me would simply NOT cooperate at all with the rules, and I would probably pay the price for it.
Back to the hair topic--I saw a gal on the train today with some most unfortunately greasy and scuzzy short hair. A shame because it would have looked cute if it looked CLEAN! I should add to this that for some people, styling short hair is actually more difficult and fussy than long hair. I rarely used to put my hair up when it was long. Doing so actually made it messier and more of a fuss than leaving it open. My hair is so shiny and slippery that it just wouldn't stay. Half of it would slide out by the time I got to work!
For those gals who are lucky enough to have naturally healthy and cooperative long hair, good for them. I envy you!
