Geometric pattern knit cardigan with front buttons. - Colors: Black, brown, beige - Design: Geometric pattern - Material: Knit - Style: Cardigan - Buttons: Front buttons There is no brand tag, so the size and material are unknown. The material is probably acrylic. It's thick and warm. Size (measured flat, amateur measurement) Shoulder width: 55cm Body width: 54cm Length: 57cm Sleeve length: 42cm I used it twice, then washed and stored it. I don't have many opportunities to wear it, so I'm selling it. I look forward to your purchase if you understand.
