This is an Adidas polo shirt I bought a few years ago. There's no tag at the neck. The size is unknown, but I think it's M-L. It's wrinkled, but it should be fine with ironing. This is a used item, so please refrain from purchasing if you are nervous or concerned about small details. I will ship it after cleaning it at home☆ ※I am also listing this on other sites, so I will prioritize the person who purchases it first.
