Women's blouse - Chinese style - size ?

Description

This is such a pretty top - 50/50 viscose / raso (satin) material. Tapestry style fabric with a gorgeous design done in green, red, and gold on black. Pre-owned, gently worn condition. Tiny hidden snaps down the front, and then decorative frog closures down the front - I find them hard to close but you could probably slip this over your head once you got them closed, and then snap the tiny hidden snaps. Mandarin collar. Brand is Simeijin. Made in China. Size is marked XXL but please go by measurements: Across the front at the underarms (bust): 20" and length down the center back: 26.5" including the collar. My guess is this is about a women's Med or Lg in the US, but please compare the sizes to your own clothing as I do not offer returns.
No issues with it, I don't even know where I got it - but it needs a home, it'll never fit me. :)
Good condition. Very neat item. I do bundle.
