Kirtles are often known as a type of medieval gown, typically worn by women. However, the term can also be used as a synonym for other clothing items. For instance, a kirtle can refer to a tunic, shift, or chemise. Some other synonyms for kirtles include dresses, robes, gowns, and frocks. These terms are commonly associated with women's clothing, but they can also be used for men's clothing. Men's versions of kirtles can be referred to as tunics or robes, depending on the style. Regardless of the term used, each of these clothing items typically refers to a long, flowing garment that can be worn for a variety of occasions.
