Usually about 1 1/2 inches in length, maybe a little less if you do a cold/cold wash. If they seem like they might shrink up too much then you could always NOT wash em. I have the streaky dry svens in a 31-32 and my natural waist is a 32. I had heard there super streachy and strech out like 3 sizes in the waist but i have not had that problem yet. I usually buy a 34 and cuff them up and to combat shrinkage but with my other nudies i havent run into that problem, usually the 34 i still have to cuff after washing. So I should expect that even if I don't put them in the dryer? I am wondering if I should buy a 34 length instead, because when I tried them on yesterday, it looked like I had at most an inch to play with (I like them to stack a bit on my boots, too).
