This is a Fila x Windsor tennis culotte. The size is M, but the waist size was larger than expected for an M, so I had it professionally altered at Magic Machine, a clothing alteration specialist. The waist measures 33cm when laid flat. Due to the nature of the fabric, there are a few small imperfections, but I think they are not noticeable. However, please refrain from purchasing if you are concerned. I am not considering lowering the price. It is also listed on other sites.
