Mauve pink and white gingham sweater top

Mauve pink and white gingham sweater top. Kinda like a vest but not really since it has sleeves. Brand is eccobay. No marked size tag but I suggest for a medium in women's. Super cute for when fall starts. Measures 17 inches pit to pit (34 inches) and it is 21.5 inches long. Bottom edge is 13 inches (26 inches). Material is stretchy. Please compare measurements to your own to make sure it fits. Used item, has been washed.
