This is a knit long dress set. I've worn it a few times, but I don't think there are any noticeable stains. The size isn't listed, but I think it's a Large. I'm not sure about the limit, but it's stretchy, so I don't think it's too tight. The neckline is close to a high neck. Long dress and coat sizes are: Dress length 120cm, shoulder width 42cm, sleeve length 55cm, waist (flat measurement) dress 38cm, coat 52cm. Please note that these are approximate sizes. Scarf is 40cm wide and 152cm long. 80% wool, 10% cashmere, 10% nylon. Please refrain from purchasing if you are sensitive to items stored at home.
