Guess the Purim Costume (On-Topic)

[WMATAGMOAGH]

Purim was celebrated this past Saturday night-Sunday in most Jewish communities around the world and Sunday night-Monday in Jerusalem and a few other select locations (the reason for why certain places celebrate this holiday a day later can be found here).  It is customary for a variety of reasons to dress up in costume as part of the celebration.  Depending on who you ask, Purim could be called Jewish Halloween or Jewish Mardi Gras.  In any event, here is a photo of my costume for this year so you all can take a guess as to what I went as this year.  (Here is a hint, if you know where I've lived for most of the past 21 months, figuring this out shouldn't be too hard.)

If no one gets it by 11:59 PM ET Tuesday, I'll post the answer.
