Again, denim should be sized during processing, and the sized denim is as neat as cardboard, and some of them can even stand up to facilitate cutting processing. Therefore, many times, the jeans of the original cloth will leave traces of chalk painting when they are cut, but they usually go through the desizing process when they leave the factory, so that the jeans are soft and consumers can wear them directly. For the convenience of some cattle breeders, many people leave the factory without desizing, leaving this process to consumers themselves, because many cattle players like to wear starched cattle, which is easier to shape, and the primary color only represents the color of jeans, so don't take the primary color as the original cloth. Personally, I think the original cloth is equal to the primary color jeans without sizing. Primary colors are only the primary colors of cowboys, at least that's my understanding. Cat whiskers are lines on jeans. Some look like a cat's beard or scratches. It's fun to raise cattle naturally. Through their own unique habits, after constant wearing, there will be a unique cat beard. This is personality, unique. For example, if you often squat, your knees will turn white radially, and there will be wallets, keys and lighters in your pockets. It will show up after a long time.
