The woman in the picture is wearing a topless dress in Tang Dynasty.
The topless skirt is a kind of semi-topless big sleeve shirt in Tang Dynasty, which is made of tulle. At that time, people described it as "slowly binding a skirt to cover the chest", "uneven shame to kill snow hibiscus" and "renewing the front edge to see the skin", which fully reflected the graceful figure and natural beauty of women in the Tang Dynasty.
Women's dresses in the Tang Dynasty basically consisted of a shirt and a raft on the upper body, a skirt on the lower body and silk on the shoulders. The same is true of the overall structure of naked-collar clothing.
Silk, also known as "painted silk", is usually woven with a thin layer of yarn with pictures and patterns printed on it. The length is generally more than two meters. When in use, it is draped over the shoulders and rolled between the arms. It's beautiful to walk and jump from time to time.
The ribbon in the middle of the woman in the picture is "leather silk".
