The size is XL in American sizes (probably equivalent to XXL to XXXL in Japanese sizes). I purchased this new in America, but I made a mistake with the size, so I am selling it new. Because it's a larger size, I think it's an item that's difficult to obtain in Japan. With a relaxed silhouette that has a moderate amount of room, it creates a stylish atmosphere just by wearing it. Also, the material uses 100% soft cotton, making it very comfortable to wear. You can wear it alone in spring, autumn, and winter, and if you use it as an inner layer for an outer garment, it will brighten up your styling, which tends to be heavy. The size is XL in American sizes. Please check the dimensions in photo 5. *Due to lighting, the actual color may appear different. The actual color is closest to the photos 1 and 2. Material: 100% cotton Because it's a thick fabric, it's also perfect for the cold season.
