Sorry, I didn't mean to imply that that's what you were advocating.
My only concern is that once you start getting the ball rolling on what's appropriate, it can very quickly degenerate into "how to look like everyone else". And I don't know where all these folks are from that set the norm, but it ends up seeming kinda preppy and very uniform.
I like your six points, though, and they seem reasonable. But when folks start advocating women to take out a second ear-ring and the like.... I think it's overly reactionary.
This goes double for dress. Most premeds on SDN seem to get frightened into the feeling that the suit has to be black or dark navy with a white or blue shirt and a power tie. If that's your thing, fine. Maybe it's age and the fact that when you're 22, you don't know how to wear a suit right (I know I didn't), but you have a lot of flexibility in dress in which you can be comfortable, feel like yourself and still fly under the radar of "conservative attire".
Women seem to have a much better handle on this than guys. Like so many things...
