I picked up and wore the TNG grey style uniform when playing the TNG role playing game inside the house with my buddies once. However, I would never go out into public with it, though. I'm just fine with letting my normal physical attractiveness and the way I dress in order to get the necessary attention when I need it to.
In other words: I take pride in looking good when I go out into public.
A Starfleet Uniform would kind of detract from that attractiveness. At least that is my opinion for us guys, anyways.
As for well formed women... thats another matter entirely. They can wear whatever sexy Trek outfit they want and get away with it. Cause guys are not really going to be looking at the uniform to begin with. Cause well... They're guys.
