you should . . .buy a long-sleeved black t-shirt

Long –sleeved black t-shirts are always useful. Let’s say you have to go hang out with some Eurotrash, or some bohemians, or you are having a Sprockets theme party, your long-sleeved black t-shirt will serve you well. Since it’s black, you can wear it to somewhat formal events. Since it’s long-sleeved, it will serve you well in a wide range of temperatures. Since it’s a t-shirt, you can play Frisbee in it. And, since it’s just a long sleeved black t-shirt, and not a long-sleeved black turtleneck, your frat boy friends might let you get away with it as well. Just be sure you don’t have dandruff. That shit will show up like the stars in a new moon sky if you’re not careful.
Be proud, fashion man. You now own one of the most versatile pieces of clothing out there.
