"The most well known bliaut examples are seen on the statues at Chartres in France. These bliauts drape in knife-like pleats that suggest they are made of silk... Both men and women wear floor length bliaut. Many bliauts include a double wrapped belt."
"See the knee length bliauts on the two men surrounding Christ. Notice the trim at neck, wrist, and hem. The keyhole necklines extends to the waist." Aibell ingen Dairmata, 2009
"The bliaud of Saint George is another good example of the tight-fitting, long bliaud of the period. Note, however, that the tunic worn by the smaller figure beneath Saint George is knee-length. This difference in length, longer for the wealthy and shorter for workmen and soldiers, was typical of the period (Boucher 164)." Click image to enlarge.
