If you are from a Class of '86 (grammar school, high school or college), what fun this can be. If you are class of '76 and you just want people to think you are class of '86, that's up to you.
The tag on this is shredded so cannot be read. Seems to be mostly, if not all-cotton. Long sleeves with ribbed cuffs. I cropped it and left the bottom unfinished. So much cuter now. You can leave it rolled or make it shorter. Hood has drawstring (if that matters). It has to be one of a kind, don't you think?

UNSTRETCHED MEASUREMENTS
