Do you ever edit you clothes closet? Just take everything out of it and judge each item: throw out, give away, or put back in the closet?
If you do that, do you have a rules of thumb like: if I haven't worn it in [a particular number of months or years], it cannot go back in the closet? What is the length of time in your rule?
Can you really follow that rule, or do you make exceptions? Is there some length of time that for you signifies vintage, which supersedes the original time-length rule of thumb?
What really old clothing items — jewelry doesn't count — do you have that you would seriously defend as vintage? And of the things you can't call vintage, what has remained unworn in your closet for the longest time (and how long)? My vintage entry: a beautiful (and comfortable) pair of black suede Perry Ellis high heels from 1981. My nonvintage item that I can't wear or part with is a long chartreuse dress made of scarf-like silk, not worn in nearly 15 years.
And yes, I'm trying to clean my closet — trying, in the sense of blogging about it, meaning to do it... sometime.
UPDATE: I'm actually doing it! In the real world! I am going to be so organized.
