A kirtle is a historical garment worn by women, often in the Middle Ages. It is a close-fitting dress that typically reaches to the knees or ankles. The kirtle was usually made of wool or linen and could be plain or decorated with embroidery or trimmings. It served as an undergarment or as a main outer garment, depending on the fashion of the time. The kirtle provided structure and support to the overall outfit, often worn with a bodice or corset for shaping the waist. It was a versatile piece of clothing that could be worn for everyday activities or dressed up for more formal occasions.
