Elvis took this Paisley shirt from his wardrobe in Las Vegas and gave it to Al Strada. Al saw a girl he liked in the showroom and asked her out for a date. She told him that she would go out with him if he get her out something that belonged to Elvis, but not a scarf since Elvis already gave her that during the show. Al Strada told Elvis about it and gave this shirt to Al for the girl.
Many time Elvis gave clothes away to friends and family and it became theirs. They wore it, washed, etc. after Elvis did. Back then the girl put it in a plastic bag and was never worn by anyone else than Elvis.
It was made by I. C. Costume Co. (also stamped on the elastic at the waist). It has puffy sleeves, elastic at the cuffs. and mother of pearl buttons.
