This might be a nobrainer but here goes -
If you were out and about en femme (not in a social setting such as a CD friendly club but just shopping, walking down the street, everyday situations) would you ever want a guy, a stranger on his own, to approach you even if it turned out that he only wanted to say how great you look? Or are there just too many idiots around?
If the roles were reversed and you were in drab and saw someone that you were quite certain was a CD, would you consider going up to them just to say hi?
For me, the 1st scenario is hypothetical since I've never been out and in the 2nd situation I've always assumed that they would rather be left alone.
