is a plain-woven textile. In the United Kingdom, "calico" refers to fabric made from unbleached, and often not fully processed, cotton. It may contain unseparated husk parts. The fabric is less coarse and thinner than canvas or denim, and has an unfinished and undyed appearance. As it is an inexpensive and readily available fabric, Calico is often used by tailors in the construction of toile — mockups of a garment for the purpose of testing a pattern.
