Proper Attire

My tickets have been purchased for the Thursday night midnight premier of The Avengers.  Gift certificates for popcorn and pretzel bites have been procured.  I have the extra wide mouth Gatorade bottle prepared to avoid bathroom breaks.


Now, only one question remains.  I will not be attending in costume, but which t-shirt shall I wear?  Captain America?  Thor?  A mash-up shirt?


So hard to chose.  I am open to suggestions.
