From Script to Screen: Seer/s Influence Map

I have a few ideas for how I want the seer/s to look. I want to go with a somewhat witch-like and mysterious appearance, with clothes that look like a clash between past and present. The seers can live a long time, so their clothing should be influenced by both past and present fashion trends. If I do end up having multiple seers in my story, their appearance will be more or less the same, with small details changed for each individual seer, e.g. older seers wearing their hair up, while younger seers wear it down.
