Ditto -- no dryer for them, and I use the gentle cycle. When I remember, I put them in a lingerie bag just to keep them from snagging on other clothes.

I also put the hosiery in there (not in the lingerie bag with the bras), but that might be a step too far. I just wear stockings too much, I guess, with my dressier outfits. They end up almost knotted sometimes, so I can't recommend it for other people's use unless you have two lingerie bags. ;)
