Royal Crew short-sleeved shirt from a department store brand. I believe the neck size is 41cm. Measurements: Length: Approximately 77cm Width: Approximately 57cm Shoulder width: Approximately 46cm Sleeve length: Approximately 25cm (Although there's no size tag, I think it's probably a size M.) The light blue stripes give a cool impression. For those considering a purchase, I'm open to price negotiations. Please be aware of the folding wrinkles.
