Green and blue striped sweater

Green and blue striped knit sweater. I think this is boy's/kid's clothing. Brand is Cherokee. No marked size tag but I'd suggest for a petite small in women's as arm's are shorter or even an XS or smaller for a baggier fit. You know when Spongebob is singing "The best time to wear a striped sweaterrrr... is all the time??" Well, this is it without the turtleneck. Measures 18 inches wide (36 inches) by 21 inches long. Pit to pit is 19 inches across. Arms are 19.5 inches long. Please compare measurements to your own to make sure it fits. I am 5'3 and usually wear a medium in women's for reference. Used item, has been washed.
