You must have some stuff in your closet that you never wear. Some of it’s probably in good condition. You just haven’t touched it in years. If it’s not your style, don’t just get rid of it. Somebody else could get good use out of it.
Find an organization that collects old clothes and gives them to the needy. Don’t give away something gross and torn, but it shouldn’t be that hard to find decent clothes in your closet that you wouldn’t miss. Somebody out there who had a tough year and couldn’t afford to buy any clothes will be very thankful for the gift.
