You can also change your personal appearance to an extent. You'll get a quest to unlock that in Limsa Lominsa--you should be able to do it now, I believe.

Yep. Level 15 quest "Beauty is Only Scalp Deep" from S'dhodjbi @ Limsa Lominsa Upper Decks - The Drowning Wench (11, 11)
After you complete it, you can change your hair, paint, lip color, and facial features (the actual category, not your facial structure) at any time in an inn room for 2,000 gil.
