This is a long-sleeved open collar shirt from SAVE KHAKI UNITED. I purchased it a few years ago at JOURNAL STANDARD relume and wore it a few times. It's a light beige color, made of 100% cotton, and is size XS. Since it's a US XS, it's likely equivalent to a Japanese size S. Length: Approximately 68cm Shoulder width: Approximately 44cm Sleeve length: Approximately 62cm Please purchase only if you understand that this is a used item.
