I'm Lucky Lucy, I put my mask on the 22nd and take it off so I look like Kitoky again until the 27th where I'm Lucky Lucy again, but no one's supposed to know until they've guessed correctly or I've revealed myself!
You basically set up two different images (sig sets!) and go to the Masquerade using your mask, but you go back to the regular sig set when the days are over.

And nonsense, better safe than sorry!
P.S. You should not have a date at the Masquerade Ball, unless your date is also roleplayed as being masked. You don't want to give away who you are by your date!!
Here are the tentative event plans!!!
