Yeah, I noticed that and was thinking you'd be interested in this too!
Best thing to search for would be "body tape", "metallic body tape", or "gold body tape" probably. The only "dedicated" source to this I know if is the guy who made it popular. You may find one-offs on random pages, but The Black Tape Project is dedicated to this type of fashion. Here are a couple of pages to check out:
Black Tape Project Instagram (tons of good photos):
