That is a great jacket! I think it will be near impossible to find the exact one or even a copy of one. He tended to shop at thrift stores- his gold sparkly jacket was a thrift store find! After doing a reverse image search and checking it out in more detail, it looks like a velvet or velour, and vintage 70's. There are some modern designers that have some similar pieces, but not exact. You might be able to source a similar print fabric and make one or keep searching and be sure to look for both men's and women's pieces! Shopthrilling has a studio service that helps find special pieces that you might want to look into as well.
