Tippet is a detail of emperor’s garment, a decorated long piece of clothing. In early Byzantine, the tipper (originating from trabea, worn by Roman consuls) was worn over the right shoulder and wrapped around the body, with its free end hanging down from the left hand. Later, when the tipper became heavy from gold and stones, it was divided into several parts - a neckpiece (maniakis, reminiscent of the barma, or yoke-necklace, worn by the Russian tsars) and a chevron, embroidered straight on the center of the dress and on the left sleeve.
