I could go for some leotard armor personally. FFXI DRG kinda had a thing like that going.

Sexy looks aren't inherently bad. The art book actually has a comment next to the Coliseum design like, "make it look like something out of cheesy 80s sci-fi", so they knew exactly what they are doing.

Yeah though, the dumb belly hole in female dragoon AF is really lame. I hope the new set they showed off for Heavensward is designed more thoughtfully.
