Definition
A gorgerin is a narrow, close-fitting collar or neckpiece, often made of metal or stiffened fabric. It was primarily worn in the 16th and 17th centuries as a piece of armor or fashionable attire. Think of it as the historical equivalent of a choker necklace, but with a more protective function. It served both practical and aesthetic purposes. Today you might see a stylized version of it in steampunk fashion.
