Is FFVII Tifa "too sexy" for KH?

Yes, but still, she CAN be mobile in jeans, right?

And in real life, can jeans really bend that much?

Depends. If she wears skin-tight jeans, they'll probably rip when she starts fighting, but if she wears loose or baggy jeans they'll only rip if they get caught on somthing.

Then let's give her loose jeans, but not baggy jeans. Somewhere between skin-tight and baggy. It looks somewhat thin, but not too thin, so they can bend to a wider range of motion. Are there jeans that are loose but not baggy?

Yup. I own some. But if I were a martial artist, I'd probably wear tracksuit bottoms or something.

Preferably, you'd wear sweat pants, but when you wear stretch jeans, they CAN be mobile and comfortable enough, right?
