I could always resort to the pinata costume from last year again.
As I was talking with a friend one day he started joking that I should be the Operation board game, following the year I had. Uh, hello... GENIUS.
I added a "popped balloon" piece to commemorate the good ol' lung collapse. Adorned my nose with a dab of red lipstick, added some 'tweezers' and I called it a success!
(PSA: Fruit of the Loom's "WarmWear" is incredibly high rise and has a very awkward extra panel that could accommodate for an adult diaper maybe? I'm not real sure. Consider yourself warned.)
At least my niece loved it!
