Pope Benedict will keep the title of "His Holiness" after he officially resigns this week but will be known as "pope emeritus" moving forward, the Vatican told reporters today. Reuters with a few more details on how he will dress during his retirement:

He will wear a "simple white cassock" and his papal ring of office will be destroyed according to Vatican tradition, a spokesman told a briefing. He will lay aside the red "shoes of the fisherman" that have been part of his papal attire and wear brown loafers given to him by shoemakers during a trip to Mexico last year.
Of course, if there are any Cardinals that happen to read my blog, don't forget to throw my name in the ring when yaw'll are voting for a new pope.
