Review and sort what you have taken out. This is especially important if you are lacking closet space. The reason you don't keep it is simply because you have not worn it in the past and you probably will not wear it in the future, so you may as well give it to someone who will. That someday has become two years or longer. This is a good time to rethink your closet space.
Wire hangers leave creases and tubular hangers take up space and can stretch some clothes.
Keep all your like items together. It makes it easier to decide what you want to wear in the morning. Keep like colors together. If you have the room, or another closet, put all your casual clothes in one area. Now you have room for any new purchases.
