I mostly wear clothes from when I was younger. A lot of it's slightly too big for me, since the family thought I was going to keep growing. I used to wear black... a lot... so my old clothes tend to reflect that while my new clothes (mostly) don't.
I tend to wear T-Shirts with a design on the front (roughly 1/3 of them related to Musical Theater, a few game shirts, some random ones I liked, and otherwise a lot of Threadless), black cargo pants, a basic hoody that says New York on it with tattered sleeves, laceless black shoes that grip my feet even when I do things like kicking, standing on my toes, and jumping around, and occasionally a pair of these.
I used to wear a brick red hoody and a red version of the same laceless shoes, but then the shoes became too battered and worn to keep wearing, and they discontinued them. Did not enjoy jumping back into mostly black clothing.
I have a new hoody in the mail that's styled differently than what I'm used to, which is a little exciting. It's rare for me to buy clothes anymore. Even if it's terrible on me, it didn't cost much and I'm sure I could find a use for it in the future.
