I literally cannot find another one of these shirts anywhere which leads me to believe it’s really something special. It’s in really good condition for its age (one VERY small spot and minimal pilling). It was made by Augusta Sportswear and is a youth large. I think it could work as a women’s XS though. It does have a name written on the back of the tag. Obviously can’t see it from the outside, but I like to mention things like that to be thorough.

Color: white/green
