If anybody wants to see what the elite were wearing at almost exactly the same time period, Schola Gladitoria has a detailed breakdown of an English effigy circa 1360-ish.

Cliffs notes version: articulated plate harness on the arms, splint and brigandine on the legs, fully articulated sabatons on the feet, coat of plates on the body with possibly a globose breastplate and mail skirt and voiders rather than a full haubergeon. Makes some interesting points about how a breastplate (a) creates a crumple zone for your innards, rather like an automobile bumper, and (b) allows room for your chest to expand and contract, making breathing in all that heavy iron much easier.
