The term 'Chihuahua Coverup' is a reference to the traditional Mexican garment known as a SERAPE. A SERAPE is a brightly colored blanket-like shawl that is worn draped over the shoulders and is often used as a decorative piece of clothing. It is usually made from wool or cotton and is decorated with intricate patterns and designs. The term 'Chihuahua Coverup' is a humorous way of referring to the SERAPE, as it is often associated with the small Mexican dog breed, the Chihuahua.
