Good-looking. Wearing green clothes makes people look younger, whiter, more beautiful in spirit and more eye-catching, so a 50-year-old woman looks good in a light green cashmere sweater. Cashmere comes from goats. It is a thin layer of fine hair that grows at the root of goat coarse hair. It grows in winter to resist the cold and falls off when it warms in spring. It is a rare special animal fiber.
