Today's popular artwork depicting Jesus is typically from the Byzantine or Renaissance showing him with handsome, idealized features, long hair past his shoulders, a beard and moustache, and a white, blue or red robe, to his wrists and ankles.  We know Jesus dressed as did other Jewish men, otherwise when Judas betrayed him, a hug and kiss would not have been needed.  Jewish and other men in the First century Roman Empire had short hair, were clean shaven and had knee length and elbow length robes.  This is in fact how Jesus was depicted in the earliest Christian artwork.
