I'm pretty much like Meredith: sniff or dirt, into the wash. I don't wash everything after one wearing at all unless something fairly catastrophic has happened (except my underpants; those get worn once). Mostly I do not buy anything that has to be dry cleaned; seeing that tag makes me decline to order or put the item back. I have a couple of things that benefit from an ironing touch-up, but it's no big deal. I'm a good ironer and it only takes a few minutes.

Otherwise, if my stuff is still decent, it gets folded or hung back up and worn again.
