This is a Polo Ralph Lauren denim shirt. The size is indicated as 3T (100). I purchased it new at an outlet about 5 years ago, wore it about 5 times that season, and washed it at home. It has been stored at home since then. This is a pet-free and smoke-free home. Actual measurements: ・Length: Approximately 40.5cm ・Sleeve length: Approximately 33.5cm ・Shoulder width: Approximately 23.5cm ・Width: Approximately 30cm *Please note that these measurements are approximate due to being measured by a layman. There are no noticeable stains or fraying, but it is a used item. Also, I am an amateur, so thank you for your understanding.
