This is a Polo Ralph Lauren zip-up knit sweater. It's navy blue with the number "3" in white on the arms. It has a used feel and there's some pilling overall, but I think it's still wearable. Since standards vary from person to person, I've set the item condition to "Slightly damaged or dirty." The armpits have a design with holes for ventilation. The width is about 47-48cm, the length is about 64-65cm, and the shoulder width is about 46cm. Please refer to the photos in the 7th, 8th, and 9th images, although they're a bit difficult to see. As it's a knit sweater, some fibers may stick to it, so thank you for your understanding.
