I love D&G... but I'm neither stupid nor wealthy enough to spend $500 on one pair... besides, if I'm going to put that much money into one garment, its either going to be a suit (which I seldom wear) or a very sturdy pair of either western boots or Harley boots.
I have some Faded Glory jeans that fit well, a pair of Levi 527, a couple pair of Levi 501, a black pair of Tommy Hilfiger jeans, and couple pair of Riders... and I buy these brands because they fit better than the rest and I didn't have to spend more than $20 a pair (got the Tommys and Levis on sale). I buy boot cut for the winter, as I wear boots all winter long here in Chicago... and I buy either loose fit or straight leg for the rest of the year.
The problem I have with getting jeans to fit... and I have this problem regardless of whether I weigh 160 or 240... is they either fit the waist but not the butt and thighs, or they fit the butt and thighs but not the waist, or they fit the butt, thighs and waist but the crotch is cut too short. I usually find the less expensive jeans fit everywhere better.
As for care of my jeans, I turn them inside out, toss them in the wash with cold water, and tumble dry on medium. They never shrink, they look and feel comfortable, and the black ones don't fade.
