The "Herlovianerslips" (Herlovian Tie) is coloured in blue and silver/white diagonal stripes running down the tie from the wearer's left. The "Gøyeslips" (Gøye Tie) is full coloured, dark blue tie with the Gøye family crest, three pilgrims' scallops. Previously, there existed a corresponding "Trolleslips" (Trolle Tie) with the Trolle family crest, a beheaded, red troll; but it has gone out of production for reasons unknown.
