Rose gold long silky duster cardigan

I’m not even sure what to call this- apparently it’s a duster cardigan, but I think formal robe could work? My bf said it looks like what the parliament on an alien planet would wear 😂 It’s super pretty and a gorgeous iridescent rose gold color. The belt weaves through the back. I actually love it but I honestly am not stylish enough to find the right outfit to wear it with. Maybe a short dress? Hope someone else can make it work! Open to offers :)
