You can wear this from early autumn to early winter by layering a cardigan or coat over the sweater. I purchased this at a department store in Tokyo. I believe it was either Isetan or Odakyu Department Store. It's 45% cashmere and 55% silk, so it feels very soft against the skin. I visually inspected it and determined there were no stains or pilling, but there is a possibility I missed something. Additional Information: I'm adding this to address inquiries about stains under the arms. I've taken close-up photos of both the front and back. Please refer to the photos from the fourth image onwards. I didn't see any noticeable stains during the visual inspection. Measurements: Bust: 86-94 cm Height: 154-162 cm Length: Approximately 52.7 cm (measured from the tag), Width: Approximately 40 cm, Shoulder Width: Approximately 36.5 cm
