Pants are super hot so I usually wear shorts unless it's snowing. I wear socks and shoes (orange or red, but on the "dull"er side and not bright and flashy). I wear shirts - either band t-shirts, t-shirts from organizations at school, etc (haven't bought a t-shirt in a store for years). I also wear collared shirts sometimes - usually black, grey, striped, or flannel. Also sometimes polos, but mostly at work since they're short sleeved and it's really hot there.
Sometimes I'll dress up and wear black pants with a nice shirt and tie. I prefer single color ties, I think it's classy but not overdone.
I have such little choice being so tall that if I find something that fits that's usually what I have to wear. I cannot be "fashionable", it is not an option. Zero "fashionable" brands would carry my size. That said, I don't think I would if I could.
