All of the clothes in your closet make up your wardrobe. If you're tired of your wardrobe, it just might be time to go shopping.
From the words warder, meaning “to protect”, and robe, meaning a “piece of clothing,” wardrobe originally meant an entire room where a person's clothing was stored. Nowadays, most people don’t have an entire room for their clothes, so the word wardrobe has downsized to just a large cabinet, or the clothing itself. A wardrobe can also be the costumes (or the costume department) of a theater company or movie.
