Good to see another Cyclone in here.
I agree quite a bit with your outlook on what people wear here, heck, I own a few AE button-ups myself as that is what I see people wearing around here.
The chino/khaki thing will just be a bit hard for me to digest as I don't ever wear that stuff outside of work, nor do any of my friends, so it would be an odd thing just to start wearing that on a daily basis, but I can try to work some in. I thought about just getting some nicer style jeans, with some brown "dressy" shoes and some nice shirts to start with. That alone would be an upgrade over my normal jeans/t-shirt/hat wardrobe. I just need to figure out where to buy such things that doesn't kill my bank account.
