This is a navy and white striped long-sleeved pullover. The front and back panels have diagonal stripes, while the sleeves have horizontal stripes, giving it a unique design compared to a regular striped pullover. Also, the back is slightly longer than the front and flares out in an A-line shape, making it a feminine design. The width is approximately 54cm (measured flat, from armpit to armpit). It has been worn several times, washed at home, and stored in a closet. There are no noticeable stains or damage, but it has been worn a few times, so there is a sense of use. Please refrain from purchasing if you are looking for something in new condition. I purchased it from the official online shop. I remember the purchase price was around 18,000 yen.
