Ruff is dress wear, pleated or crimped collar or frill. This is usually wide and full. It was loved to be worn in Europe in the 16th and 17th centuries. The ruff was at that time catered as a symbol of aristocracy. A gathered or pleated piece of fabric forms the ruff around the neckline. The ruff is known as the millstone collar. Ruffs serve as changeable pieces of cloth which could be laundered easily. The stiffness of the garment forced an upright posture, which is why they were considered the symbol of wealth too. Modern versions of the ruffle collar tend to have smaller heights, often of just 1 inch (2.5cm).
