You know what, sure, let the guys wear the Minfilia suit too. I was saying Minfilia's gets a pass because there's probably a technical limitation (it was designed for a female model mesh and adapting it to men would be a non-trivial amount of additional work), but at the very least male lalafells could definitely wear the Minfilia suit (because, spoilers, the guy-a-fells largely share model shape and animation, and thus armor meshes, with the girls) so screw it, let the guys wear the Minfilia outfit. Do the modeling work and make it happen.
My point is that none of these other Scion outfits need to be gender-limited, because they're all based on existing armor meshes. The gender limitations are completely arbitrary.
So they should add more tailored-for-men unique armor sets. There's no reason to slap arbitrary restrictions on a lot of this gear.
Of course the real problem is that they should just allow guys to wear the effing dresses if they want and do away with a good number of the gender restrictions, but since that doesn't seem to be on the cards...
edit: a little extra clarification!
