Dress yourself up like a girl, then look at yourself in the mirror and talk to your reflection.
Boy, this brings back memories. During homecoming week in high school they had a competition among the 4 grades. One day was called Dress Up Day, where you could dress up nicely to earn points for your grade. Well, I was a 20-year old senior who at the time just didn't give a crap about any of my peers (whom I didn't really know, having lost 2 years due to "issues").
So I borrowed my sister's blue dress, put on a string of fake pearls, and walked to the bus stop. I still remember that one kid who said, "Dude, why are you wearing a skirt?"
"It's not a skirt. It's a dress," I replied.
"Why are you wearing a dress?"
"Because it's dress up day." And for some reason that ended the conversation.
Of course this was before I started losing my hair, so I had beautifully wavy shoulder-length locks to complete the image. And it was rather awkward changing in the boys' locker room before and after gym. And in my Latin class I overheard a girl saying what was probably the best compliment I'll ever receive:
"He has better boobs than I do."
