The term skort (a portmanteau of skirt an shorts) is used idiomatically in some regions. While some garments sold as culottes resemble short trousers, to be a skort they need to look like skirts. They are distinguised from trousers or shorts by a fuller cut at the bottom (hem) than at the waist. Skorts were developed in order to provide more freedom to do activities such as gardening, cleaning, or bike riding, and give the appearance of a skirt. Skorts are popular in sports such as tennis or golf, and are often part of girls' athletic uniforms. Some skorts are essentially skirts with a pair of shorts hidden underneath, while others resemble a pair of shorts with a panel of fabric over the front.
