I can only think of one thing I had that was recognizably female, a pair of jeans, and I wasn't even out of the closet yet when I got rid of them. One day I was on a city bus sitting near some guys my age, and I felt such humiliation about the way I was dressed. I knew they didn't see anything weird about it, but it was awful. I'd only worn them in the first place because my then-boyfriend liked them. I donated them to a local social services agency.
Now I don't have girl clothes, but I don't really know how to dress like a guy, either. I'm not seeing a lot of commonality among male passersby on the streets, though, which makes me feel better about my sartorial aimlessness.
