I don't know...I was raised by parents who were not poor but very, very thrifty, and my clothes mostly came from thrift stores or KMart. Occasionally as a big treat they'd buy me something from Old Navy (!).
And as a high-school kid, it's really trying to make those kind of clothes look decent when your peers have much more expensive clothes. I went to a very affluent school, so the difference between how I looked and how most of the kids did was really striking.
I think feeling bad about how I was forced to dress has played a big part in making me the (yeah, I have to admit it) fashion-obsessed person that I am today. I manage to stay in my budget, just barely, but I know that fashion and having specific pieces from various collections is FAR more important to me than it is to normal women. It's like I still have this inferiority complex that makes me feel like I have to be the best dressed woman in every room.
And I think if my parents had been willing to spend a little money on me and buy me nice things once in a while, back then, today I wouldn't be as obsessive about this stuff. I still don't know why they dressed me (and themselves) like they did when they're multimillionaires. Nowt so queer as folk, y'know...
