Information:
Two almost identical versions were made of this suit, which were both worn during the 'Aloha shows'. Apparently, the suit Elvis wore during the rehearsal show was slightly bigger. It's also the version Elvis wore later on tour (and in Vegas) in 1973 and 1974.

Three belts were made for this suit; the first one was never worn on stage, as Elvis gave it to actor Jack Lord as a gift before he ever got to wear it. The second belt was identical to the first one, and it was worn during the two "Aloha shows". The third belt had some minor differences, and it was worn everytime Elvis wore the suit after the 'Aloha event'. Elvis also wore the 3rd "American Eagle Belt" with the "1974 American Eagle" jumpsuit in May 1974 (on tour and in Tahoe)

The cape that was worn with the "1973 American Eagle" was not the original one. The one that was originally designed for the suit, was way bigger, and way too heavy for Elvis to use on stage (pictures below).

Nowadays EPE/Graceland has both of the suits, one of the (three) capes, and the 'third belt'. A private collector (LM) owns one of the capes, as well as one of the first two belts, apparently also Ed Parker has one of the capes & belts on his possession. Also the original long cape is in private hands. It was sold during one of EPE's auctions.
