I have a closet trick that really Works For Me. At the start of each season, I have to move my current season from the top rack to the bottom since I'm a bit vertically challenged. As I do this, I turn all of the hangers backward. As I wear an item and bring it back from the wash, I turn it the other way. This allows me to see what I truly wear. It helps me vary my daily wardrobe by reaching for items that I haven't worn, and it allows me to eliminate what I fail to choose. The items that are never turned are removed and donated.
I hope that this idea helps you discover what you really love and wear and weed out those items that don't speak to you anymore.
