Cotton denim is a durable fabric made from cotton twill, known for its distinctive weave that creates a diagonal ribbing. This versatile material is typically dyed with indigo to achieve the classic blue color associated with jeans. Beyond its iconic use in jeans, cotton denim is also employed in various clothing items, including jackets, skirts, dresses, and shirts. Its strength and breathability make it suitable for casual and workwear alike. Additionally, denim can be treated or blended with other fibers for added stretch or texture, expanding its applications in fashion and home décor, like upholstery and accessories.
