I love adult wear!
Of course, you need to be selective and appropriate - not right to wear it on a place with kids and or very strict people... but its always fun to wear it between friends.
Funny how people outside from this business get excited when you say you work with porn. LOL
PS: GOOD fabric on the T-shirts is a must! Companies seem to make t-shirts and not care much about the quality of it, and IMHO it could give a bad impression about the company.
