Why is it you can take a $30 pair of <insert item of clothing here>, slap the name of some loopy designer on them, and suddenly they're worth their weight in platinum twice over? Maybe I'm too pragmatic but that makes no sense to me at all, along with paying a huge markup just to give Frumpy McFashion some free advertising.
Someone who equates price to quality bought me a pair of "designer" jeans once. Inside of six months they were useless (a giant hole in a naughty area had formed). The $30 pair of jeans I bought out of the Land's End catalog three years ago still look like the day I got them. They fit better, too.
I care about quality. I could care less about whose name is on it.
