Embroidered Pink Button Down Blouse

This is a button-down blouse that my friend brought back from traveling. I’m not sure where exactly it’s from, but it’s pretty cool. It has some nice embroidery and it’s lightweight and soft. It has some discoloration in the underarms (see pics) but it is washed and clean 😊 if you have any questions please ask! It says it’s a size M but it DEF fits like a US small, so I’m calling it that!
