A long skirt is a type of garment that covers the lower body and typically extends to the ankles. The two most common types of long skirts are maxi skirts, which are floor-length, and midi skirts, which reach to the mid-calf. Maxi skirts are usually made of lightweight materials such as cotton or silk, while midi skirts are often made of heavier fabrics such as wool or denim. Both styles can be dressed up or down depending on the occasion.
