If you only have one hanging rack, add a second one below it, just high enough so the clothes hanging won't drag on the floor. I don't hang anything longer than a blouse or man's dress shirt. If you have dresses that need to hang you can fold them over a hanger, or if you don't wear them very often, store them in a covered bin under the bed or in the basement.
Use the slim non slip hangers...you will be amazed how many more items you can hang with these verses the plastic hangers. Fold jeans, T-Shirts etc and place in bins on the shelf above the bar or wherever you have some shelf space if you don't have room in your dresser drawers.
