First, to distinguish between positive and negative:
Because the original design style of autumn trousers is clothes with tight hands, feet and wrists, the style is relatively uniform, but the body shapes of boys and girls are different, so the requirements for clothing are different. In order to increase the comfort of boys wearing long pants, an opening design is simply added to boys' long pants.
Second, used to distinguish between men and women:
The opening design in front of boys' autumn trousers has played a role in distinguishing men from women and still plays a role in daily life. For example, when we buy autumn trousers in the supermarket, we can see at a glance whether they are men's or women's, which also provides convenience for consumers.
Third, it is used to dissipate heat and increase air circulation;
I believe everyone knows that it is inevitable that the temperature will be too high when you put on underwear and long pants, so the opening design of long pants also plays a role in heat dissipation. In winter, most people spend a long time indoors, and the indoor air circulation is poor, so the opening design in front of boys' autumn trousers also plays a role in increasing air circulation to some extent.
The origin of autumn trousers:
The origin of autumn trousers is the North American continent. It is said that the first patent of autumn trousers design was obtained by Canadian Frank stanfield. He and his brother started with cotton underwear which is known as "non-shrinking", and formally applied for the patent of autumn trousers on 19 15 12.7, becoming the father of modern commercial autumn trousers.
After 19 18, countries returned to daily production, and European and American countries deepened the industrial revolution according to the idea of assembly line and division of labor. In the past, manual workers with full-body activities were divided into workers with more upper body activities and workers with more lower body activities. Even shirts and trousers were not as good as autumn clothes for autumn trousers, and autumn trousers ushered in their own spring.
