I'm not really a T-shirt kinda gal ....although I did buy something kind-of piratey looking for pirate night on our DIsney Cruise.
DH is a plain T-shirt kinda guy. He doesn't want to be a walking ad for anyone (his words!). For Christmas last year (knowing a disney cruise was coming) .... we bought him a ton of t-shirts for our DisneyCruise - Lightning McQueen, Buzz Lightyear, Goofy, and Grumpy .... the kids love it!
We've got dreamworks coming up ... and I'm looking for Shrek and KFP shirts, both for DH and the kids.
My kids are young, so they love the "character" clothes.
Sorry Venice, but that is as close as I get to answering your question!
