The "Cabbie Cap," also known as a newsboy cap or flat cap, is a rounded cap with a small, stiff brim in front. Traditionally made from wool, tweed, or cotton, it features a button on top and is often associated with taxi drivers and working-class men in the early 20th century. This style of cap has seen a resurgence in fashion, appealing to both men and women. It is versatile and can be worn casually or dressed up, making it a popular accessory in various cultures around the world.
