Information:
The bird on the "Phoenix" suits wasn't originally designed as a bird. The original design was supposed to be two zebra heads bowing into each other, but when Elvis saw the sketches, his comment was "that bird has funny feet", as he was looking at the design upside down. So a bird design it came... but if you look at the design upside down, you can still see the two zebras in there.
When Elvis first wore this suit, he didn't wear it with the original belt, but instead, with a light blue version of the "Lucky Belt"
Nowadays the suit is owned by EPE/Graceland, they had it on display with an 'alternative belt' (designed for the suit). This was one of the four "Phoenix" suits: Black Phoenix, Silver Phoenix and Red Phoenix
