A wardrobe can refer to a set of clothing or a piece of furniture -- sort of like a freestanding closet.
Most wardrobes have a section for hanging clothes. Many also have drawers, shelves, a mirror and places for jewelry, make-up or other items you might use when getting dressed. Some wardrobes have wheels to make them easier to move around.
