Flared skirts, also known as A-line skirts, are a type of skirt that is fitted at the waist and gradually widens towards the hem. They are usually knee-length or longer and are often made of lightweight fabrics such as cotton, linen, and silk. The name 'A-line' comes from the shape of the skirt, which resembles the letter 'A'. Flared skirts are a popular choice for formal occasions, as well as everyday wear.
