I can't say I care too much about clothes. As a kid, though, my mom never really bought me enough clothes, and I being a boy would rip my jeans up easy and the like, so I ended up doing lots of halfass sewing jobs, as my mom didn't know how to sew. So like, a lot of the time I looked like crap due to that. Once I got older, I started buying all my clothes myself at Salvation Army, and after wearing new, but crappy Walmart clothes, I started loving name brand clothes, I was pretty amazed at how well, say, an Abercrombie or Hilfiger shirt fit me compared to the Hanes in a pack, dirt cheap, too, most shirts I got for like 50c or so.
The only real quirk I have is for boxers, my favorite boxers are oddly American Eagle boxers. They fit me the best. Every other boxer is made for guys with small thighs, so generally I fit a small/medium waist size for boxers, but more along the lines of large for the leg holes. I really wish I could "upgrade" all my boxers to nice fitting American Eagle ones, instead of the Hanes and Fruit of the Loom ones I wear most of the time now, but to solve that problem I just cut an inch slit on the side of the boxers.
Oh, for shoes, I now prefer like cheap crappy Canvas shoes over like, more modern kinda sneakers. Also for a time, I wore boots a lot. And for socks, I prefer black socks. One odd thing I do now is sometimes I'll wear dress socks with sneakers, as I have to wear dress socks for ice skating, and overall dress socks are more comfy, but the problem is they don't absorb sweat, so your shoes smell, so now I wear dress socks under my athletic socks.
In general, I don't really wear super tight clothes, but I also don't like wearing loose clothes, either. Loose clothes actually make you look fat imo.
But those are my preferences.
