every year our drumline buys matching shorts for band camp.

Every year during our band camp the guard has a different dress up thing each day. They're themes like disney day, class color day, decade day, movie day. and my favorite... make fun of the staff day. last year our trumpet section leader dressed up like our 300+ pound vis tech... and ran basics. Everyone was laughing so hard we got nothing done.
only time our vis tech was on time!

I've seen skirt day (yes, the males too) patriotic day, 80s day, redneck day and a bunch of others. (Those are just the ones that come to mind.)

Last week for band camp, the drumline had crossdress day (I wore a dress =p), rockstar day, gangster day, and pajama day. None of them were really good except crossdressing.
