Surcoats
The Surcoat can be seen on Ki-Adi Mundi and Sarrissa Jeng in the Geonosis Arena in Episode II: Attack of the Clones. A surcoat may be worn over the outer tunic for both Jedi and Sith, must have a hood, and should be closed in some capacity in the front, though no visible fastener should exist. The surcoat must be constructed so that it is capable of covering the whole torso, even if it worn partially open above the obi. Tabards must still be worn either over or under the surcoat, as the surcoat is not a replacement for either tabards or a tunic.
Surcoats may be colors from primary colors, and may have linings with colors from the secondary colors.
Surcoats function as an optional accessory, as all normal costume elements are still required.
