This is a knit dress from Y's yohjiyamamoto. The open back design is perfect for layering. The material is 100% wool. It's shown with a shirt dress, but the listing is only for the black knit dress. I bought this about 20 years ago, and it's a wonderful design even now, and I think it's quite rare. Measurements are taken flat: width 55cm, total length 113cm. The open back provides room, so it's essentially a free size. The condition shows some pilling and fuzzing. Please check the images. Please consider this item as used and understand its condition before purchasing.
