For anyone who doesn't know, a vanity armor slot would change your look without changing the stats. For example, I could wear my King's Fall helm in my normal armor slot and a helm that looks cool but has worse stats in the vanity slot. I would get the stats of the King's Fall helm but my character would look like she was wearing the good-looking helm. I don't like how any of my characters look with their best armor. I would prefer to use armor from Year 1, since almost all of it looked better.
