This is a Polo Ralph Lauren short-sleeved T-shirt. It's a boys' XL, size 170. I bought it about 5 years ago, after reading online that it was equivalent to a Japanese men's S-M. I wore it about 5-6 times when I bought it, and washed it at home, but I haven't worn it since and have kept it stored at home. There are no smokers or pets in the house. Overall, I don't see any stains or tears, but please understand that this is a used item. Actual measurements: Length: Approximately 71cm Shoulder width: Approximately 45cm Sleeve length: Approximately 23cm Width: Approximately 47cm Please note that these measurements are approximate, as they were taken by a layman.
