Autumn trousers and cotton trousers, as warm clothes in winter, keep warm very well. But some people may think that there is no difference between long trousers and cotton trousers. In fact, the main difference between them is: 1, the materials are different. Autumn trousers refer to those worn when the temperature is very cold. Usually, you wear a pair of autumn trousers inside and then put a pair of trousers outside them, while cotton wool trousers refer to those made of cotton, chemical fiber, camel hair and other warm materials. 2, wearing different methods, autumn pants are generally worn when the temperature turns cold in autumn, so it is also called autumn pants. However, cotton-padded trousers are thicker and have a three-layer appearance, so they can be worn directly alone, and their warmth retention effect is better than that of long trousers. There is actually another difference. Autumn trousers are a northern proverb, while cotton-padded trousers are a southern proverb.
