I have a couple Philadelphia Phillies shirts (where I grew up) and a Sea Isle City sweatshirt (favorite shore town), but I no longer live anywhere in the area.
It’s almost hard not to when there’s so much awesome local stuff.
I have a sweatshirt with my undergrad initials on it, and a few other articles of clothing with my grad school’s name (which is also the name of a state) on it.
But other than that, no. I think it looks tacky.
More than likely, you’ll end up with the standard Austin Uniform Shirt.
