What I wear on a cruise is what I would wear at home. I will never have "The Costanza Cruise Collection".
(referring to the closet of "resort only wear" that George's parent's had on Seinfeld.)
I no longer go with the tuxedo because I no longer need one in my "land life". I would rather spend the $$$ on a dark suit that can be worn on multiple occasions.
I often have to buy new clothes for a cruise because the old ones are worn out.
