"Some of the fashion was dictated by the ever-increasing stoutness of the prince of Wales (or "Prince of Whales," as he was known behind his back). By the time he reached his thirties, the prince had taken on such a fleshy sprawl that he had to be forcibly strapped into a corset... All this pushed his upper body fat upward through the neck hole, like toothpaste coming out of a tube, so the very high collars fashionable in his day were a kind of additional mini corset designed to hide an abundance of chins and the floppy wattle of his neck."
Now you know. :)
