Short distressed denim

What is Denim? Denim is a cotton fabric manufactured using a 3- or 4-ply twill weave, with the warp threads being the same color and the weft threads being unbleached, bleached, gray, or a lighter color than the warp threads. This is not merely a fashion term; it is clearly defined in the Japanese Tariff Schedule. In other words, not just any blue cloth is denim. Even if the colors are similar, if the combination of threads or the weaving method does not conform to the regulations, it will not be classified as denim for tariff purposes. Note that this regulation is intended for the classification of imported goods, and wearing trousers that do not meet the conditions does not make it illegal. Furthermore, there are no specific legal regulations regarding whether denim has holes in the knees, how many times the hems are folded, or whether it suits the wearer. Therefore, **while Japan has established clear standards for the warp and weft thread colors of denim, it leaves the wearer's fashion sense entirely to their own judgment.** The above is the legal definition of denim.
