Remember the Floor Space

"If you have lots of long-hanging clothes, the whole bottom of the closet can become a no man's land," says Morgenstern. "Group your short-hanging pieces at one end of the closet and your longer-hanging clothes at the other—that will open up lots of floor space, where you can place a little dresser or a stacking shoe rack."
