I've worn a baseball cap for as long as I can remember. Inside, outside, at the pool table, and dinner table. Heck I probably slept with my hat on. I came back to APA league from a long time off, and joined a random team, who turned out to be a great crew.
About 2 years into playing with that team I was in a tough match during playoffs. I sat down collecting my thoughts, removed my hat, and turned to look at my teammates. The girls had a shocked look on their faces, and the guys start laughing. I don't know what that was all about, and continue to play. When the match wraps up, I turn to my team and give them high fives, fist bumps, etc. As I approch the girls with shocked looks on their faces they say "OMG, you have no hair! YOU'RE BALD!"
I did wear a garter belt for one league competition and it worked for me.
