Everyone knows the rules. If you haven't worn it in a year, out it goes. Same for anything damaged, holey, stained, just plain worn out. Easy, right? Well, if it is, why do so many of us have closets filled to bursting with clothing, most of which fits in one of the afore-mentioned categories?
Making decisions is exhausting. It takes a lot of mental energy to decide whether an item is worth keeping or should be donated or thrown away. The larger the closet, the bigger the pile of items to go through, the more energy it will take. This is why it is crucial to go through your closet and dreser at least once a year. If you make that a yearly habit (even better, four times a year with the change of seasons), you will find it easier each time. You'll actually remember that you had decided to keep that red t-shirt another few months, and that you never actually wore it. Easy decision now, out the door it goes.
Using drawer dividers can even further simplify this task. You can take care of one division of shirts, underwear, socks, etc. in about fifteen minutes (the magic time amount, according to the FlyLady). You'll enjoy a feeling of serenity as you let go of items that don't fit your lifestyle or size or changing sense of fashion.
I had hung onto several t-shirts that I remembered really liking, but hadn't worn for a while. Why didn't I wear them? Rises changed, becoming lower. Thus, a t-shirt that formerly fit nicely and allowed adequete coverage no longerlooks right with today's lower waisted jeans. So, easy decision once I realized it: out the door!
