Ladies Vintage Chinese Embroidered Silk Long Sleeve Blouse 10-12

Ladies vintage cream coloured Chinese silk long sleeved blouse with embroidery and silk covered buttons. The make is Jade Lantern. The size stated is 18 but it is a lot smaller…more like a 10 or 12. Please go by my measurements: 54cm across the chest, 56cm across the hem, 44cm straight across from shoulder to shoulder, 57cm down the sleeves. The sleeves are slightly puffed with gathering at the cuff. All buttons are present and the blouse does not appear to have been worn. Probably from the 70s or 80s.
