Back in 2014 before the game launched Matt Firor I think said that we would be able to change apperance mid game at some point, he posted this on the elder scrolls reddit Q and A session.
Its been like a year, and no update has included this. I'm sure the team might need to spend a bit of time to implement it, but the character creation system is already present. Just let us edit our characters body and face, similar to the dye station. Have a building or station to edit our charcs.
When will this be added? It was promised a year ago, and nothing happened since...
