This is a Ralph Lauren shirt with a Big Pony embroidery. It features a refreshing light blue cotton fabric and a classic, simple silhouette. The colorful pony embroidery is the design's focal point. It's a US kids' size M, so it should fit well for those who wear a Japanese women's size S. Please check the actual measurements for details. It's perfect for wearing on its own or layering for a coordinated look. It's been worn only a few times and is in excellent condition. I believe you'll still enjoy wearing it. ◆Size◆ Kids' M ※Measurements are approximately equivalent to women's S Shoulder width: Approximately 39cm Length: Approximately 65cm Width (underarm to underarm): Approximately 42cm Sleeve length: Approximately 52cm ※Please note that there may be slight variations due to the flat-lay, amateur measurements. ※To prevent any issues, please feel free to ask any questions before purchasing. ※This is a used item managed by an individual, so please refrain from purchasing if you are not accustomed to used clothing, are sensitive to such items, or are looking for a new item. ※When shipping, we will compress the item to make it as compact as possible.
