The Tang Dynasty, of course. In the Tang Dynasty, fatness was the beauty, and women were fond of plump bodies. The Tang Dynasty was the heyday of feudal society in China, and both people's thoughts and material production reached a historical peak. At the same time, since the Tang Dynasty, flower patterns have been widely used in craft decoration, with lively and free composition, well-proportioned density and fullness. In particular, the combination of wavy continuous patterns and flowers and plants is a popular branch-tying pattern in Tang Dynasty. With such a beautiful pattern, girls are of course willing to spread it to show their beauty.

However, although in the Tang Dynasty, fatness was beauty and fullness was beauty, it never reached the point of "bare breasts". Some information has been obtained to prove that only Korean women can show their breasts in the history of East Asia. In the Tang Dynasty, only girls from big families were "topless", especially in the Wu and Zhou Dynasties, when women could be emperors, this state reached its peak.

In the Tang Dynasty, it was natural, beautiful, fashionable and noble. Scholars at that time also recognized that women showed their beauty. There are many poems describing women's charming posture in the Tang Dynasty. In Ou Yangxun's Nanxiangzi in the early Tang Dynasty, there was a sentence of "chest as snow, face as flower". There are other literati's poems, such as "Snow on the chest for a long time", "It's too clear and snowy in pink-chested Shimada Hanzo", "Suzaku hangs down and floats into the blue water" and so on.

Moreover, in the tombs unearthed in the Tang Dynasty, many women painted on murals are plump, and their daily low-cut dresses and tube tops are very elegant and loose, pursuing the elegant sense of Wu Dai's fashion, advocating the free development of the body and full of vitality, which is also in line with the aesthetic standard of "taking fat as beauty" in the Tang Dynasty.
