Rusticus did the opposite. He was among those who encouraged Marcus to set aside the vanity of status and dress down whenever possible rather than walking around in the formal attire of a Caesar (and later an emperor). This was exceptional behavior for a Roman of his status, incidentally, but the British Museum has a statuette in its collection that seems to confirm it really happened. It shows Marcus dressed not like an emperor but as a common citizen, apparently while visiting Egypt late in his life.
