At the time, the tour did not include the upstairs living quarters. His aunt was still living there and may still be today. Elvis left in his will that his family could remain living there as long as they want after his death. Part of the tour featured his many costumes and jumpsuits. Elvis was big on jumpsuits.
Fat people like to wear jumpsuits or muumuus because they are easier to get dressed.
Evis chose the jumpsuit over the muumuu. It was hard to take him seriously toward the end of his career, with Elvis in a muumuu it would have been impossible. He would have looked like Dom DeLuise with sideburns. One of my favorite parts of the display was the Elvis underwear collection. It is a secret display but if you slip the guide a fifty he'll show it to you.
