Materialistic Values?

Why do some people feel that expensive brand name clothes is the only good kind out there? Ive met so many people here, and there are people in my family, who think price determines quality... Thats not always true I think tho... Almost all of my clothes comes from walmart, target, and small stores in PR. Its been that way all my life. This girl walked up to me and asked me why I dont wear Tommy, CK, Polo, or anything like that. She said Walmart clothes arent nice... What the hell does that mean? Does that mean I dress well? Wow... Well nothing else to write about. Im boring I know lol.
