While Im not saying those are all wrong facts and that you are also right with what you counted up, there is still a difference how players would go with their own preferences and character designs. I want the game to stay with its aestethics as it is. You are right, females can wear the stuff from Cloud and Squall. But there is still a difference how the characters will look with players likes and given limits.
All you summed up is technically something with proper aesthetics or in a funny manner. Now turn this picture into a male Roegadyn with pink Lightning hair and tight female clothes or even a dress, skirt whatever. Big difference right?
And another thing; in FFVII Soldier Clothes weren't meant for Cloud or male figures only.
