Cindy is basically the first female character you get to have significant interaction with in Final Fantasy XV, and while she’s not a warrior I’m going to make an exception here because.
1. She’s supposed to be the lead mechanic who can fix anything
2. So far I haven’t been able to find any noteworthy warrior women in Final Fantasy XV
3. Most of the female characters wear slightly differently styled clothes based off everyday and formal clothing from the real world
I think it’s safe to say there’s no way that we’re supposed to believe this is an outfit a third generation mechanic would wear to work (particularly in a world where monsters roam about just a hundred feet or so from truck stops)
If you have any doubts, I suggest checking out this great project where a fan artist gender flipped the cast and check out how Cindy came out:
