I’ve got options for you, you can pick your favorite but they all make the cut!
There’s the gold metallic foil spandex fabric from Fashion fabricla in the US, I personally use the brand for some of my clothes and they have quality products that’s why I thought to recommend here’s the link to purchase, also a customer photo review of the product so you know what it looks like https://www.fashionfabricla.com/products/gold-metallic-iridescent-foil-spandex-fabric?_pos=10&_sid=c00c8997e&_ss=r
