This is Alisha Diphda, from the upcoming JRPG Tales of Zestiria. The thing that gets me about this outfit is that the tabard she’s wearing actually looks like it could have some chainmail and padding under it (as in, it’s one of the first female military outfits I’ve seen in a JRPG that’s not skin-tight), but then everything goes out the window for the strange lack of pants and the bizarre armour-garters. Like, she actually has a decent amount of armour on, but then she just… forgot pants…
I’m pretty sure if you had “garter belts” to hold up thigh high boots they’d ridiculously annoying and have a good chance of chafing you. I looked up this character (mostly to confirm if the little crosses meant “medic”) and I”m pretty sure this is yet another outift where “panty flashes” were the top design priority.
