What is the proper attire for......

Alright, so, goin to semiformal with the SNu chapter here in Omaha this Saturday. Sunday, the girl i'm dating and i are going to check out "Noises Off" here at the University Theatre.

My question is this, what is the proper attire for a Sunday afternoon matinee at a University theatre? Khakis and a button-down? Nice pants and a dress shirt? Jeans too informal? Don't forget, this is South-Da-FREAKIN-Kota and it's butt-ass cold here. I don't want to look like a cretin, but don't want to be overdressed for a Sunday afternoon.

Please, hit me with your thoughts.
