This patterned shirt was purchased second-hand about 10 years ago to be used as a dance costume. It has only been worn a few times. There are no brand or size markings, and there is no tag. All the buttons have the same anchor design. The size is such that a slender man who is 170cm tall and weighs 60kg can wear it comfortably. The length is a bit long, and the sleeves are just right.
