I've gone to my Meetup outings in a girl costume probably a dozen times. But I don't go out as a regular girl. I go out in some kind of fantasy girl costume. I've been a Hooter's waitress, Wonder Woman, a mermaid, a Geisha girl, a harem dancer, Victor/Victoria (a mon pretending to be a woman pretending to be a man), among others. I love developing the costumes.
Once, there was a group of GG flight attendants waiting for their ride to the local airport. I walked up to them and said, "I really like your costumes."
