This is a uniform skirt that my older sister used to wear at her company. Please use it for work, such as under a suit. I also wore it a few times for my part-time job. The uniforms change frequently, and they also vary by season, so it's in relatively good condition. The uniforms are made every year at a well-known, long-established department store in the prefecture. It's a size 9, so I think it's about a size M.
