I purchased this a few years ago and wore it for about 2 hours. It's a long-sleeved long dress from H&M. It's EUR36 UK8, so I think it's a Japanese size S. It has a waistline, a 44cm slit in the front, and the back is open up to the waistline. It closes with two ribbons. The cuffs also have 10cm slits and are fastened with decorative buttons. Spare buttons are also included. It's 100% polyester and doesn't wrinkle. Shoulder width: 39cm Sleeve length: 56cm Length: 117cm Front width: 46cm Measurements are approximate and may have some errors. The length reaches about my ankles, and I am 158cm tall. This is a used item that has been stored, so please understand and agree before purchasing.
