The Gatsby Cap, also known as a newsboy cap or flat cap, is a rounded cap with a small, stiff brim in front. It is typically made from wool, tweed, or cotton and features a button on top. This style became popular in the early 20th century and is often associated with the working class and rural life. The cap gained further popularity through its association with the character Jay Gatsby from F. Scott Fitzgerald's novel, The Great Gatsby. Today, the Gatsby Cap is worn as a fashionable accessory and is often seen in vintage-inspired outfits, reflecting a nostalgic style.
