Some good ideas, though I don't necessarily see the things you object to being enforced much these days:
1. The girly-white uniforms: thank God we don't have to wear white at our hospital, or other nurses would be doing vascular checks on me, looking for diaphoresis, and running for a thermometer... yeah, white's no friend of mine in the fashion department! Our hospital has a ciel-blue policy for RNs, to which most of us adhere, and which happily (for some) equalizes us and allows the patient to be able to discern between RN, housekeeper, tech, MD, etc. I still get called "doctor", though, but that's another thread...
2. Our graduation just had us standing at our seats, holding a candle and reciting an oath, none of which seemed feminizing to me at all. All schools do things differently, though, so I can't comment on yours.
3. The clothes: yeah, not much to choose from. Pretty much unisex, as far as I've seen. Not really a good fit on any of us, but fergoshsakes it's just a uniform. I've never seen a "nursing watch", though. Just get a watch w/ a second-hand! That's pretty much what everyone uses.
It doesn't hurt to remember that there are plenty of professions where women are entering the field in recent decades and where they still aren't made to feel like they fit well. As a side note, my other career is as a musician (guitarist), and I still hear phrases like "the guys in the band", "the fellas on the bandstand", etc., even if there's a female instrumentalist there. The unspoken assumption in many people's minds is that if women are involved in music, they're "singers", and if they are vocalists they're expected to be more or less hood-ornaments for their bands (the classic picture of the chanteuse on top of the piano, etc.), which is completely screwed up, but it's a reality nonetheless. Meanwhile, there are plenty of female instrumentalists who'll blow you away with what they do! I can't even imagine what it's like having to go against that tide, professionally, and this doesn't even touch on the pushback that female police officers must face every day when there's so much more on the line. Just food for thought!
