My T usually wears business casual type clothing--slacks, button shirt, not usually a tie. Occasionally he has worn black jeans. But once during the winter, he stood up, picked up a bag, pulled out a vest and put it on and sat back down. I wanted to laugh but it was too early in my therapy and I wasn't comfortable enough. Now, I'd crack a joke for sure! I think Sunrise's T is a vest guy too.
Oh yeah-- and I always remember the description of Pinksoil's T wearing the cheese cube shirt.
