A tress of hair is a plaited length of human hair, knotted at the ends. It’s a period charge, found in the canting arms (Italian trecce) of de Trecio, c.1550 [BSB Cod.Icon 270:825], and in the badge of Zouche, c.1520 [Walden 163]. The illustration shows a simple looped tress, as in the badge of Zouche; the arms of de Trecio show the tress with the ends of the loop crossed in base, which fact is blazoned. See also knot.
Katja the Forthright bears as a badge: A looped tress of hair Or surmounted by a single-sided comb sable.
