Not much. I got a pair of Adidas track pants today for around 30 bucks. Also a pair of dark blue skinny jeans from Old Navy for about 30 bucks as well.
I don't spend over 60 bucks on shoes, and I only buy like 1 pair every year. Same thing with jackets, but I spent about 200 bucks on a pea coat once. About 100 on a leather jacket.
Hot Topic and other stores usually have good sales on band tees/merch, so I don't mind throwing down 20 bucks on a nice tee shirt to support my favorite artist/band.
I occasionally wear button up / business casual shirts too, but I don't think I spend much on that stuff either. I'm pretty frugal and minimal when it comes to fashion. I don't even wear watches.
