Vintage Free People button up, sz small

Great vintage “mid-century” patterned free people shirt. Great, unique piece. It does not have a size tag, the only tag is shown in the photos but it fits like a xs or small. For reference I’m 5’2” & usually wear a size 4/small and the shirt is fitted on me. The material is almost silky but has stretch to it. No signs of wear or damage. I will post measurements and more photos soon.
