A tux is a tux, but I am sure they have a little selection and certainly wouldn't hurt to ask them. I heard on the news there was a place like that doing a hallows eve (halloween) sale, but can't remember the name of the place. It might be listed on KGW's website since that is the channel I was watching at the time.
btw, I know there are different types of tuxedos, but a shop like that should have a variety since you can't rely on prom to be your income all year around.
