Is Jessikah's Mithra style locked to an Assault Breastplate, or is that a different body that looks similar?

Assault Breastplate, Empyrean Bazubands, Brontes Cuisses, and Adhemar Gamashes. Not visible are my dual Kilij, the Beast Slayer and Isador.
I happened to get the Brontes Cuisses from the Special Gobbiedial and liked how they looked, so I built a lockstyle set around them. FFXI doesn't have a lot of blue armor, and a lot of it isn't even the right shade, but I was happy with how this turned out. The set was originally designed for Warrior, but I thought it looked like a cool "medium-weight armor" Blue Mage set. Which suits me fine, because I'm better than my trusts are at tanking most of the time anyway.
