The Ivy Cap is a flat cap made from various materials, including wool, tweed, and cotton. It features a rounded crown and a small, stiff brim at the front. This style of cap is often associated with casual and smart-casual attire, making it popular among both men and women. Originally worn by the working class in the early 20th century, the Ivy Cap has since become a fashionable accessory. It is sometimes referred to as a newsboy cap or Gatsby cap, and is often seen in vintage-inspired outfits or worn by characters in films set in the early 1900s.
