Not always drag, but I love to do costumes with gimmicks, that I always make myself. One year, for a college student party, I dressed as a homeless bum, in a long Army surplus overcoat, grungy pants and shirt, a dirty face with 3-day beard growth, and knit cap. I put the unopened bottle of wine I was bringing for the party in a brown paper bag.
After ringing the front door bell I quickly squatted down in the doorframe, all huddled over clutching my wine bottle in the paper bag. As the door opened I tipped over onto my side, falling into the hallway and making groggy sounds.
"Oh, God, Alex, come quick!" yelled the girl who answered the door. "There's a wino out here at your door! Hurry!"
Alex ran out with some others, everybody excitedly trying to decide what to do with me, call the police or what. Finally Alex started to get me to my feet, while I was making incoherent drunken noises and stumbling.
Finally standing up steadily, I said in a clear, normal voice: "Happy Halloween, Alex! Here's some wine for your party!"
Surprised shouts, groans, laughter, and cries of "It's Tom!" as they recognized my voice, if not my appearance. I was quickly brought inside, and the other guests called around to see my costume, which every new arrival had to do. But I had one more trick up my "sleeve."
Once everyone had gathered around, and we all laughed about my dramatic entrance, I grabbed the front of my overcoat, ripped it open and flashed them all!
My "pants" were actually just pant legs to my knees, cut off some old trousers, and held up by elastic bands. My "shirt" was likewise just the collar and partial front of an old shirt, all you needed to see under the heavy overcoat. But I was too timid to actually be nude, instead wearing skimpy Speedos. Still, made for a nice shock.
And for the rest of the night, girls & guys alike kept coming up and asking me to give them a "private flashing" which I was glad to do. LOL!
