Something that I think is wonderful about the white mage is that you have quite a bit of leniency when it comes to design. A lot of people base their costume designs off of the videogames (I like the original FF white mage personally
). However, so long as you're wearing white edged with red triangles most people will make the connection. So if you can't find a canon white mage design that suits you, then you can always create your own! I've seen several people do that with some awesome results ^_^.
