The first layer consists of leather armor: a leather chestpiece, shoulder, elbow and knee pads, leather grieves, leather skirt and and leather padding on the inside of the second layer's boots.
The second layer is the base armor layer. Over the previous layer of armor, Janna wears a black metal breastplate, as well as dark metal vambraces, pauldrons and gauntlets. Said vambraces have latches attached to them to hold The D's (It stands for 'Defense'). She also wears a studded leather skirt, a la Roman skirts.
The third layer functions more for utility purposes and a certain amount of style. On her back she has two crossed sheaths for her weapons, Honor and Justice, held in place with leather straps going across her chest. On the sides of said straps she has small metal latches for the D's, effectively making her already large frame seem even bigger when the two shields are attached. While she doesn't wear a helmet to keep her vision unobstructed, she wears a black metal diadem of a relatively simple design on her head.
