I recently bought this cargo pant. http://www.gap.com/browse/prod.....=791585002

They felt, and I thought fit well. I love the detailing on them. So I wore them today, but by the afternoon they were totally bagged out in the knee, butt, and lower abdomen areas. Now I'm wondering if I should have tried the next smaller size. Since I won't be able to return a worn item, should I try drying them to shrink them up a bit? Or am I just out of luck? Any other ideas?

(This is when online ordering and living in a rural community really stinks.)
