Personally, I always wear black jeans with a black leather belt. Often, I'll wear a black (sometimes white) band t-shirt, black leather Austrian military boots, and a black leather jacket. Occasionally, I'll wear some skateboarding sneakers. I just purchased a *guess color here* leather trench coat, but I don't think I'll have many reasonable opportunities to wear it, ha ha.
I also just designed and printed this on a white t-shirt today:

I'm honestly very proud of the design. The shirt came out pretty well, too. Making my first noise-related band tee inspired me to make this thread.
