I just read a tip that I thought was interesting. For organizing your closet and getting rid of things you don't wear.
You basically buy 2 different colored hangers. And you start everything out on one color. When you wear it, wash it and return it to the closet, it gets put on the other color hanger. Then at the end of 6 months or a year clothes still hanging on that original color hanger get an evaluation of why you even have in your closet since you didn't wear it.
My personal thoughts on this though...having all those extra hangers around from that first set would start to annoy me. I hate having lots of empty hangers they get all tangled into each other. But it is a good way to actually SEE what you wear - having that tangible visible proof that something didn't get worn is harder to ignore then just living in denial and saying oh I will wear it soon.
