Natasha Rostova has her first ball and dances with Pierre Bezukhov:
"Pierre, isn't it grease on your collar?"
"Oh my, how could miss such a terrible flaw in my costume, I'm totally destroyed" & walks away.
Then she dances with Kniaz Bolkonsky:
"Andrew, isnt't there a dip of sauce on your tunic?"
Bolkonsky faints. Finally she's dancing with Rzhevsky:
"Poruchik, your boots are all covered in mud!"
"It's not mud, it's shit. Don't worry, mademoiselle, it'll fall off once it dries up."

Окса, абсолютно верно. Только бери маску поручика. Ему жить легче. Делай то, что от тебя никогда не ждали.
