My sister used to do promotions for a radio station, so all my t-shirts are cheaply made advertisements for shitty movies like Cloud Atlas, Rock of Ages, Monuments Men, Trouble with the Curve, etc., each with the movie title and logo on the front and the release date on the back. They spark a surprising amount of conversations about said shitty movies, which has spurred me to go out and watch the shitty movies so as to be able to respond when people start talking about them with me.
My favorite is my Rock of Ages shirt, because it is soft and it has the perfect length to it. I hate that so many t-shirts nowadays are seemingly made for obese people, resulting in t-shirts that are super wide and short. I prefer them to be narrower and longer, going down to at least the belt loops of my jeans.
