Years ago and I'm talking 35 or more, I read Color Me Beautiful. It recommended you organize your closet by color, which I have done ever since. Within the color group I organize by item: skirts, pants, jackets, tops, etc. keeps me from buying the same thing over and over. Shoes in original boxes with labels by color and type. Sweaters and knits folded in drawers color coded too. Casual clothes in separate cabinet. Off season under the bed in storage bins and in closets downstairs.
