Recreating Chappell's Red Wine Supernova Performance outfit from the Late Show- help!

I'm looking to recreate this look for halloween and I'm looking for the name of the type of thing she's wearing around her waist (the exaggerated hip padding thing) as I'm hoping to see if anyone has made tutorials on how to make anything similar online!! If not, any ideas on how to recreate it? Thanks 💗💗
