The most important factor that a closet should have is the ability to hold items that need to be held in it. That is, hangers for a coat closet or shelves for a linen closet for example. An organized closet of any size should make it easy for you to locate items, keep items in it in good condition (think wrinkles here), and should be able to save you time when it comes to placing items in and taking items out of it. Having an organized closet can also help reduce stress as closet that is cluttered or messy can be a source of stress.
