My new style is kind of like this. Mostly I wear a lot of guys clothes. But I will wear a hint of pink in my shoes (with a hot pink nike symbol) or wear a pink bracelet or something. I had a pink bag I was carrying around to work despite that most of the clothes I wear are straight-up men's. I've thought about the possibility of painting my nails but a less feminine color, instead of pink or red, more like black or green or turquoise and still wear men's clothes and maybe a hat. The bag really throws people off because I'll dress like a man but wear pink. They don't understand genderqueer or I-just-don't-care.
Be unique! What's wrong with that?
I kinda like giving off mixed signals.
I like to paint my nails in bright colors for exactly the same reason. I used to stick to dark colors, but now I can enjoy some flamboyant ones. :) If I'm wearing mostly masculine or mostly feminine clothing on a day, I like to have something small to contrast in there.
