The loros (Greek: λῶρος, romanized: lôros) was a long, narrow and embroidered cloth, which was wrapped around the torso and dropped over the left hand.
Although in practice it was, according to the De Ceremoniis by Constantine VII, worn only in exceptional occasions such as on Easter Sunday, Pentecost, sometimes other feasts, and to receive important foreign visitors, the loros was an integral part of imperial portraiture.
[8] The loros was also worn at Easter by the "twelve dignitaries", holders of the ranks of magistros and anthypatos, as well as by the Eparch of Constantinople and the zoste patrikia during the ceremonies of their promotion.
[13] Westwards, a mosaic in the Church of Santa Maria dell'Ammiraglio shows King Roger II of Sicily wearing "the raiment of a Byzantine emperor", including a loros.
[14] The Stola, a 14th-century garment in the Imperial Regalia of the Holy Roman Empire, was made to be worn like a loros, but misinterpretation caused later generations to wear it in the manner of a priest's stole, although it was too long for the purpose.
The hanging end was longer and much broader, and after reaching down to the ankles turned upwards to be folded over the left forearm, or fastened or tucked into the belt.
