I purchased this costume from a costume maker at a flea market about 6 years ago. My husband bought it because he thought it was cute, but I never wore it, so I'm selling it. It's unused. The waist is 36cm when laid flat (so 72cm around). It doesn't stretch at all, so please be careful. The pants have a zipper closure. It appears to be 100% silk. Inseam is 62.5cm, and the length from the waist to the hem is 92.5cm (I think I had the length adjusted for myself). The collar has a stiff collar stay. There are small stains on the front and sleeves, which I will wash and report on later. → The stains on the cuffs are gone! The stain on the lower abdomen of the front is lighter, but still slightly visible (see image 6). I will fold it up small for shipping.
