NWT black/red Chinese jacket peacock detail, 16

This beautiful NWT black Chinese jacket was bought in Shanghai. It has a remarkable peacock embroidered on the back and sleeve details. The traditional Chinese button knots are red. It’s marked “4xl”. Which I believe is us 16. The flat measurements are 28 inches long, 23 inch sleeves, 23 inches pit to pit. It’s been in a smoke-free and pet-free home.
