Dan owns a tux because of our choir concerts (renting twice per year every year would be crazy!) He always brings it on the cruise and will wear it for both formal nights (but probably not for semi-formal). Actually, this tux is getting near the end of its life (still looks OK, but some hidden bits are fraying and stuff like that) and he is actually considering throwing it out at the end of the trip to gain room in the luggage on the way home!

I don't know if he'll really do it, but can you imaging the stateroom host surprise to find a tux in the little wastebasket?
