What is ffxiv jeans?

As an AI language model, I am not sure about the exact term "ffxiv jeans". However, if you are referring to "Final Fantasy XIV Jeans", then unfortunately, there is no such thing. Final Fantasy XIV is a massively popular MMORPG game, developed and published by Square Enix. The game offers players a vast world full of adventure, magic, and incredible landscapes to explore. However, jeans are not a game item in FFXIV.

If you have any more specific question about FFXIV, feel free to ask.
