I got a pair of AG jeans from Nordstrom a few weeks ago after hearing rave reviews from posters from here and the Nordstrom saleswoman. I have to say that after several wears, I am really unimpressed. They seem to stretch out just as much as my Gap jeans. I've had Sevens, Citizens, and Joe's jeans in the past and none of them stretched out as much as the AG jeans. Is this normal??
