Take them back to your dry cleaner, where most of them originated. If you haven't done so already, bite the bullet and buy some skirt hangers. There is nothing worse than being in a hurry in the morning and trying to wrestle a safety-pinned skirt off a hanger. This is a simple habit to create and does wonders for the look and efficiency of your closet. When you get garments back from the dry cleaners, throw away that horrible plastic drape.
Shoes are also a problem for most people.
I really like to work with shoe racks that hang on the back of a door or on a wall. I also like shoe shelves, if you have the space for them at the bottom of the closet. Inevitably, your closet will fall into disarray again. This happens to everyone, even professional organizers. In order to forestall this, make a point of going into your closet once a week and doing a little housekeeping for three or four minutes.
