Collar days are designated days on which the collar forming part of the insignia of certain members of British orders of knighthood may be worn. Collars are special large and elaborate ceremonial metal chains worn over the shoulders, hanging equally over the front and back, often tied with a bow at the shoulders, with a distinctive pendant attached to the front.
Collar days in the United Kingdom
Collars are worn by members of the Order of the Garter, the Order of the Thistle; and Knights Grand Cross of other orders (the only active ones being the orders of the Bath, Saint Michael and Saint George, the British Empire, and the Royal Victorian Order; the Order of Saint Patrick, the Order of the Star of India and the Order of the Indian Empire are now in abeyance).
The collar can be worn on specific 'Collar Days' throughout the year.
Collars are also worn when the Queen opens or prorogues Parliament, and a few other observances; including religious services of the various orders, and by those taking part in the Ceremony of Introduction of a Peer in the House of Lords.
Collars are not normally worn after sunset, nor while mounted in parades such as the Trooping the Colour. Even if a bearer is entitled to more than one collar, only one may be worn at a time. The riband with badge can not be worn with the collar, but that of another order is allowed.
