Vintage Button Up Blouse

This is a very retro looking blouse. Almost looks alike an old grandpa design on the shirt. There is no material or size tag in the shirt. The material is very light and breezy, probably a rayon. It has a cute boxy cut. Colors are off white, tan and orange. Would fit 12/14. See below! Measures approximately Pit to pit 22” Length 25” Might be vintage!
