This is a black skirt that was worn as a uniform for office work. The size is 40, which is equivalent to a size L or 11. The fabric isn't quite jersey material, but it has a moderate amount of stretch, so I wore it often. The waist has a button closure, but it has some elasticity. If you look closely, you can see the shiny marks from ironing on the back. Waist (laid flat): 33.5 cm Length: Approximately 53 cm Skirt Office Uniform Suit
