Butterfly long sleeve knit top

Butterfly long sleeve knit top. Brand is Betty Rides, vintage. Marked a size small in women's. Cream color with green stripes. So amazing! 100% acrylic material. Flaw: does have some pillage. *price is firm* Measures 16 inches pit to pit (32 inches) and it is 18 inches long. Sleeves are 19.2 inches long. I am 5'3 and usually wear a medium in women's for reference. I definitely suggest for a small as it was a bit tight around the chest and arms for me. Please compare measurements to your own to make sure it fits. Used item, has been washed.
