A caftan, also spelled kaftan, is a long, loose-fitting, floaty dress that has been worn by a number of cultures around the world for thousands of years. It is a variant of the robe or tunic and is similar to long-sleeve tunics, but caftans have wider sleeves and are made from a variety of fabrics, including wool, cashmere, silk, cotton, and more. The garment is often worn as a coat or as an overdress, usually having long sleeves and reaching to the ankles. In regions with a warm climate, it is worn as a lightweight, loose-fitting garment. The style, uses, and names for the caftan vary from culture to culture. In some cultures, the caftan has served as a symbol of royalty.
