Long-sleeved shirt with navy and white stripe design, Ralph Lauren, size 4. - Brand: Ralph Lauren - Design: Stripe - Size: 4 - Color: Navy/White - Style: Casual Purchased last year at a Ralph Lauren outlet for about 16,000 yen. Size is US size 4. Shoulder width is 38cm. I wore it a few times and haven't worn it since, so I'm selling it. It's a bit slim and makes your body line look beautiful. The material is 69% cotton and 31% linen, which is perfect for wearing as is, or for wearing under a cardigan or sweater in the fall and winter.
