Chinese blouse

This blouse was purchased on a trip I took to China. It’s marked an extra extra large, but it fits like a small medium. I’m not quite sure what the fabric content is although I’m sure it’s partly polyester. Lovely little clear round buttons at the front and a sheer standup collar. Very nice construction And in good condition. It has been hanging in my closet for many years. I’m not even sure if I wore it possibly once or twice. The florals on the front seem to be embroidered onto the fabric.
