An UMBRELLA is a rain shield, which is an item of clothing used to protect the body from rain. It is typically made of fabric stretched over a metal frame and held open by a mechanism. The fabric is usually waterproof, so it can effectively keep the rain off the person wearing it. Umbrellas come in a variety of sizes and shapes, and are often brightly colored or patterned. They are commonly used in rainy climates, but can also be used as a fashion accessory.
