No matter what closet design you choose, you can easily customize the shelves, racks and compartments to suit your lifestyle. (Even if that means you don't make the most of every single square inch.) Instead of choosing a vertical wall rack for your shoes, why not display your collection along the horizontal shelves if you have the extra room? It adds a boutique look to your walk-in and keeps your shoes in tiptop shape. Photo courtesy of The Container Store.
