If she's a thief, why she is a wearing single metal shoulder pad and a metal buster...or the metal leg armour for that matter?
Those pieces wouldn't be very flexible, and the belt looks pretty clunky as well. The sheer amount of gaps in the armour would leave her with no protection; in fact her heart abdomen are completely exposed. Even in fantasy most thieves will cover those areas, they just use lighter armour with more give. I get wanting something to look unique and all, but a lot of this outfit makes very little sense, unless the main focus here is for her to use seduction based abilities.
