I'll be honest, I notice and care. I don't like brands, especially not popular ones, or ones with huge logos. The biggest store i shop at is Old navy and it's only for leggings or cardigans. I wouldn't wear a shirt with a big logo and I refuse to go in stores like aeropostale or Abercrombie.
What I do notice is if his clothes are wrinkled. I also notice how clean he is and if he styles his hair or not. If a guy looks clean and we'll presentable, I notice. If you're looking all ratty I notice.
Most I could tell if it's good quality and/or an expensive suit or article of clothing. As far as knowing brands not so much. I would not be impressed if he's an unpaid spokes gigantic logo wearing douche.
Yeah sometimes I notice I don't really care though. I mean cool story bro if your jeans cost more then mine do. I notice fashion more then brand you can wear cheap clothes and still look good. It just means better quality and what not I don't really care.
I do notice. What he wears can tell a lot about his social background and personality. If he's constantly in designer clothes I can tell he's from a reasonably well-off family, might care a bit more about looks, and the brands do have their own sort of personality type, the people they attract. I mostly notice if he wears pretty much the same outfit constantly, and get curious. Is he just that unconcerned about looks? Not enough cash to spend on something other than long pants? Maybe religion or he might be like me, a bit self-conscious.
I don't care. If it looks cute on you and you have good style, and you're attractive.. HELLO! I could care less if you bought it at Walmart, if it looks good, I like it. This is coming from a upper middle class 16 year old senior in high school. I could care less. If you can rock the outfit, I don't care how much you spent on it.
I care if it's for a relationship :p not so much for friends, but the reason for that is that I am a metalhead and that I would only want a boyfriend who has a bit the same lifestyle as me. So, for me, a boy should wear band tees :p
I use to care, but now only a little. I'll buy good shoes, underwear and suits. But everything else, walmart, old navy etc. is where its at. and having an impressive physique will make any woman forget about the brand of shirt you're wearing.
