I agree, don't say anything blunt, however little compliments are wonderful!

I go out on a regular basis and pass pretty well. Once in a while, people have said things that they meant well, but it didn't land well with me. For example -- one time a genetic woman CROSSED THE STREET just to walk up to me and say, "You look so put-together!" ... in her mind she was being awesome, but all I could think was, "So you could tell from all the way across the street that I'm a crossdresser?" ... whereas another time, a genetic woman simply asked me for directions, I provided that, and then she kind of looked me up and down, paused for a second, and said, "You've really got it going on!" ... which was authentic and made me smile.
