What is the specific term for the garment that closely resembles the one worn by the groom in the Arnolfini Portrait?

The view is built with extremely fine brushwork and shows a number of highly detailed buildings and hills before snowcapped mountains.A lance rests against the shoulder of a youthful-looking St. Michael. Michael is dressed in elaborately jewelled and coloured armour, his left arm holding his helmet, while his right hand rests on the shoulder of the donor as he is presented to Mary. The donor kneels in prayer before the Virgin, with his hands held upwards as if in prayer, although they are not clasped.

Similar carvings are seen near the donor in van Eyck's earlier van der Paele and Madonna of Chancellor Rolin, and where they depict events or personal circumstances from the donor's life. Those in the present work likely serve a similar role, however because the donor is unidentified it is unknown as to what they may refer. Elisabeth Dhanens speculates that they might depict the sarcophagus of Hippolytus in Pisa, which she believes adds credibility to the belief the donor was of Italian origin; she also notes the military scene reflects St. Michael's status as military commander. Ward compares the carving to a similar one found in the Washington Annunciation. Unlike in van Eyck's earlier votive portraits the donor is positioned at a remove from the Marian apparition, and at a much...
