I mostly don't even think about brands. But I'm totally non-fashion-conscious. I think the jeans I'm wearing right now are Wrangler, and the shirt is the Target house-brand. shrug
No, so I may not be your target market. The only thought I usually put into something like a shirt, is I'll buy a t-shirt of a band I like, or one that has a cool logo/slogan on it, or whatever. That's about it.
