Kerchiefs are a type of headwear that can be worn for both fashion and practical purposes. They come in a variety of shapes and sizes, and can be made from a variety of materials. Two common types of kerchiefs are bandannas and SCARVES. Bandannas are typically square-shaped and made of cotton or silk, while SCARVES are usually rectangular and made of wool or other fabrics. Both bandannas and SCARVES can be used to keep the head warm, protect the hair from the sun, or simply add a fashionable touch to an outfit.
