For charrs and asuras, male and female armors models are just resized: beside that, they looks exactely the same.
Also, Sylvari, Norn and Human have the same models for male/female (excluded maybe Male Norn, which has a oversized torso), which means that an armor on a female Sylvari is actually like the same armor on female Norn or Human.
Thus, 4 armor types are enough to get a full view of options:
-Charr (male and female share same armors)
-Asura (male and female share same armors)
-Male Sylvari/Human. And a bit misproporzioned, Male Norn.
Obviously, not counting the different looks due to body types/sizes.
