<Li> The collar is worn around the neck, over the mantle and is secured with white ribbons tied in bows on the shoulders . Like the mantle, it was introduced in the 15th and 16th centuries . Made of pure gold, it weighs 30 troy ounces (0.933 kg). The collar is composed of gold heraldic knots alternating with enamelled medallions, each showing a rose encircled by the Garter . During the reign of King Henry VII (1485 - 1509), commencing at the termination of the Wars of the Roses, each garter surrounded two roses--one red for the House of Lancaster and one white for the House of York--but he changed the design to encircle the Tudor rose alone, a combination of both forms . Today one of the most visible representations of the collar forms part of the monarch's heraldic achievement on the gates of Buckingham Palace . </Li> <Li> The Great George, which is worn suspended from the collar, is a colourfully enamelled (sometimes jewelled) three - dimensional figure of St. George the Martyr on horseback slaying a dragon . </Li> <Li> The Garter is worn on ceremonial occasions around the left calf by knights and around the left arm by ladies, and is depicted on several insignia . The Garter is a buckled dark - blue (originally light - blue) velvet strap, and bears the motto in gold letters . The garters of Stranger Knights and Ladies were once set with several jewels . Two styles have been used: one is a working garter where the end slips through the buckle and then is tucked in a specific way and the other style is a' pre-made' one that has the buckled and tucked end pre-fashioned and is fastened with a clip attachment . </Li> <P> Up until the middle part of the 20th century, it was customary to wear Tudor style under - dress, consisting of white silk embroidered doublet, breeches, full hose, white doeskin pumps with satin bows and a sword belt with sword, under the robes . Nowadays, morning dress or a lounge suit is worn, except for coronations when Tudor under - dress is worn by the canopy - bearers . </P>
