This is a T-shirt by illustrator LAM. I obtained it as a used item and displayed it for a while before storing it in my closet. It seems to have been released at a Singapore event in 2023. I believe it's quite difficult to obtain now. I've listed the size information I found online below: Shoulder width / Body width / Sleeve length / Length Shoulder width: 50cm Body width: 53cm Sleeve length: 22cm Length: 74cm Item/Type: Apparel
