I wound up ordering from Amazon. These are the products I ordered:
Vest: https://www.amazon.com/gp/product/B076Q6N3B2/ref=od_aui_detailpages00?ie=UTF8&psc=1
Skirt: https://www.amazon.com/gp/product/B07CLPHTS7/ref=od_aui_detailpages00?ie=UTF8&psc=1
I found a fairly nice blouse at Goodwill that I think works, so I don't have to do any sewing with the exact fabric. Good luck!
Also, I got this wig at Michael's for $4!!!
