Well my character had went to Gridania and had learned conjury. However when she joined Ul'dah garden (Much against her tribes wishes lol) and explored the Sunken Temple of Qarn, which was a temple of azeyma back in the days when white and black magic were pretty common, she found a soul crystal of a white mage of old. In fact the soul contained inside was one of the teachers.
So that is how she became a white mage. As for the white mage clothes, the Seedseer when she returned to Gridania and showed the crystal and told of what the crystal had taught her, realized she could not unlearn what she had learned. So they taught her why white mages became limited, and trained her in the more modern style so she doesn't follow the path the white mages of the past took, which nearly destroyed Eorzea.
That's just an example of how I worked it to still comply with lore.
