Although listed as a size M, I think it's actually a size S, so I'm listing it as S. Width: 43-44cm, Length: 62-63cm Both are unused, but the tag for the navy one is missing. This is a set of two. ① Black x Gray x White Smooth T-shirt material ② Navy Skipper design (V-neck) Pique-like polo shirt material Both are thin. Upon close inspection, there may be some slightly rough stitching, but these are new items purchased online and are offered at a low price. Please refrain from purchasing if you are particular about details.
