I know we're mostly talking about dressing up here, but I thought I would toss a little something in.

Our local (cub scout) pack didn't require the boys to wear uniform pants, instead they wanted the boys to wear jeans. So I wore my denim Utilikilt. I never did get a uniform shirt, because I decided not to be a leader.

I like all of the hats choices that have been that have been suggested in this thread so far.
