Generally speaking, the smaller the D number, the thinner and more transparent the stockings are. The more durable socks are, the higher the D number is. Generally, 40-60D are spring and autumn socks, and over 60D are winter socks. In summer, the denier of stockings is generally below 20D, which is cool, light and transparent.

The earliest clients of stockings were men. In the16th century, European courts and upper classes began to be obsessed with colored pantyhose. According to the fashion at that time, men used to wear pantyhose generously to show their thighs, which was considered as a symbol of beauty. From David's The Coronation of Napoleon I and the Queen, we can see that even on solemn occasions, princes and nobles will show their legs and unanimously choose tight stockings.
