This is a Merino wool crew neck cardigan from MUJI. This is the higher quality item, priced at 4990 yen, not the 2990 yen version. I wear the same one, and it feels great against the skin. It's thin, so it doesn't show under outerwear, and it's 100% wool, so it's warm and goes with any color. It's useful all year round except for summer. It's a new, unused item, but it has some fold creases. I don't think they'll be noticeable when worn, but please understand this before purchasing. Size: XS Length: 56.5cm Sleeve Length: 56.5cm Width (measured from under the armpits): 43cm Color: Oatmeal (a color like a light gray-beige) Related brands: United Arrows, IENA, Journal Standard, Spick & Span, Traditional Weatherwear, Lavenham, Mackintosh, Mackintosh Philosophy, Saint James, Margaret Howell MHL, Human Woman, O'Neil of Dublin, Birkenstock, Charpentier de Vaisseau, Saint James, Agnes b., Agnes b.
