My theatre group held a Masked Ball one year, and it was trivially simple to tell who was who—even the guy in the full-face Venetian mask was obvious. And when I was in 'Cabaret' I was in the gorilla suit, and people *still* knew it was me... (!?) Making shows like 'Die Fledermaus' a teensy bit silly, though I dare say the rules are different for operetta.

I suppose Shakespeare had a set of twins in the company at least part of the time - one of them in a dress, one in breeches, fair enough.

I do love Pining, so bad breakup -> not over it -> polish their claws on each other definitely works for me!
