It's a well-known rule of adventuring that while male heroes wear full-body armor, females need to wear thongs and chain mail bikinis that barely cover their body.
Heck, in some games the same armor will cover much less when equipped by a female hero then when a male wears it! Yet, it provides the same protection...
Obviously, this is magical armor.
(If your read Vixine, they make fun of this quite often).
