I have a large trunk in my room that I use to store the linens in. I toss the item to be re-worn over it. That way it is off the floor and makes a nifty cat bed
: Also, I occasionally re-hang the item then hang it on the back of my door. That might work for you, that way it is not in the closet to be mistaken for being totally clean, and yet it is up off the floor.
I only wear skirts, and I usually wear them at least twice. It depends on what I am doing that day, but I don't usually get them dirty enough to warrent washing each time. My Grandmother told me that you wear your clothes out more in the washing machine than on your back.
