Which fiber is known for its fine, lustrous quality?

Silk is renowned for its fine, lustrous quality, making it a luxurious and highly sought-after textile in the fashion industry. Its natural sheen is a result of its triangular prism-like structure, which allows it to refract light beautifully. This characteristic makes silk an excellent choice for formalwear and high-end garments, as it elevates the overall aesthetic with its shimmering appearance.

In addition to its luster, silk also has a smooth texture and excellent draping qualities that contribute to its appeal in various fashion applications. It's often used in items like evening gowns, lining for jackets, and scarves, where a high-quality finish is desired. The combination of its delicate and elegant look, along with a soft and smooth feel, solidifies silk's position as a premium fiber in clothing and textile production.
