IMHO, an outfit that detailed should be considered to be a work or art. Therefore, if one would like to make a poser/3D re-production of an item like for sale, the original creator should ALWAYS be contacted for a permission. Even if it wasn't exactly required by law, it would definitely be considerate and respectful. I had no idea about the connection, being unfamiliar with the FF games, but I came here to see this thread when Byrdie mentioned it at DAZ forums. But it is undeniable, that the outfits are nearly identical.
