Blue jeans are a type of pants made from denim fabric, known for their durability and comfort. They typically feature a five-pocket design, with two front pockets, a small coin pocket, and two back pockets. Originally designed for miners in the 19th century, blue jeans have become a staple in casual fashion worldwide. The color "blue" comes from the indigo dye used in the denim, giving them their signature look. Over the years, blue jeans have evolved into various styles, including skinny, bootcut, and relaxed fits, appealing to a wide range of personal tastes and fashion trends.
