Blue jeans are durable, versatile pants made from denim— a sturdy, twill-woven cotton fabric known for its diagonal ribbing and long-lasting wear. Traditionally dyed with indigo, they feature the classic five-pocket design, metal rivets for reinforcement, and a button or zipper fly. Blue jeans range from light to dark washes and come in various fits such as skinny, straight, bootcut, and relaxed, making them suitable for casual everyday wear or more styled outfits. Their ability to fade uniquely over time gives each pair a personalized, lived-in look, which is a big part of their timeless appeal.
