I don't agree that SE lacks 'tawdry males' as the OP says. If anything I think this game has some of the best variety in both male and females. The garleans will always provide heavily armoured villains, male and female. You have fully clothed, albeit still seductive villains like Yotsuyu, Tsukoyomi. Eikons have a wide variety of body types and clothing styles. Shiva, Sophia and garuda are scanty, but so are ifrit and titan. In both cases you have near naked, highly attractive males and females following the generally accepted norms for beauty (lithe, curved females and muscular, imposing males). For clothed you have Lakshmi, Titania, Ramuh.
There's also pretty boys, like Omega and Alphinaud (clothed), final Kefka (near naked)- and a large selection of ascians and garleans who are overly handsome, plus a wealth of highly unclothed potential future bosses when they draw from previous final fantasies.
And then, there's also a large number of 'ugly' bosses and characters. I can see the argument that there's more feminine clothing and scantily dressed females than there are males, but I don't see how that's a problem when the variety is still clearly there, and for everyone from bosses to allies to our own available glamours. If you want to be fully armoured or wear an outfit that shows no skin as a female, you have numerous options- if you want to be hardly dressed as a male, you have numerous options. I'm sure males do have more full armour choices of course- but I'm also quite certain that more males are using those options, and on the flip I'm certain there's a more sizable number of females using more revealing outfits than males. In that sense I think SE has done this perfectly- both taking the majority's desire into account by providing a great amount of options for them, while still providing choice for the more niche aesthetic desires.
