I think I'm going to have to implement a similar rule myself. My closet is full. I really like 75-80% of it, and the rest is meh. My question is this: when you get a new thing, does the thing you get rid of have to be in the same category? Like, if you get a new skirt, do you get rid of an old skirt, or can you get rid of a pair of pants instead?
cheers
