First, distinguish between positive and negative. Men's autumn trousers have no style, and they are basically the same. In addition, some trademarks will be on the side of autumn trousers, so it is difficult to distinguish the front and back, so it is easy to distinguish the front and back by adding a hole.

The second is to distinguish between genders. At first, the styles of men's and women's autumn trousers were basically the same, so in order to better distinguish the sexes when buying, this hole was designed in front of men's autumn trousers.

The third is to increase heat dissipation. Because of the physiological structure, men need more space in the lower body, otherwise they will be bored and cause diseases after a long time. Therefore, designing a hole in autumn trousers can increase comfort.

In addition, the holes in the autumn trousers can also be used to dry clothes, which is quite useful to avoid stretching the sides of the autumn trousers. In addition, some men's autumn trousers have buttons on the holes, most of which are older styles. When they are older, they tend to urinate frequently, so the openings with buttons are generally larger, which is convenient for going to the toilet and can also prevent deformation.

Wear it with pointed shoes, which was very popular at that time. Later, people found it very comfortable to sleep in these breeches, so the function of breeches gradually became "pajamas", which is now autumn trousers.

/kloc-in the 0/8th century, the warm-keeping facilities in North America were not perfect. In order to keep warm better, people wear long pants that are designed to be connected, which is both warm and shaped. But after a long time, people found that this jumpsuit was warm, but it was inconvenient to work.
