Yeah that's a little much for me, and I've gotten as accurate as I can get on my spectrum. This is the belt, and if you have an actualTandy store near you, they usually have this in stock:
Embossed Floral Vine Belt Blank 1-1/2" (38 mm)
Since I'm a glutton for punishment, I've opted to remake her main costume and use the old skirt for Wyatt Dolores.
I've gathered all remaining screen accurate bits I can possibly get as of late. The chemise lace I already had and found last spring through an online California store for only .95 a yard. It's since sold out as more of the community caught on, but you might be able to find it again searching 'Cluny lace'.
Then a friend ended up finding the the gimp trim and the chemise lace at a Tennessee fabric store for super cheap as well...after I hand dyed/painted 6+ yards of gimp trim last year
.
A friend of her's also found the petticoat hem lace from a small fabric store in California. (The velvet trim is my original trim that I purchased from Mood.)
The replacement fabric I've found isn't 100%, and it isn't as dark in person, which is fine since her blue shapeshifts with the light as well. There was a costumer at Dragoncon this year who had pretty much the exact fabric, which she claims she found on Etsy. (I've searched and searched, all terms...as the fabric isn't 100% flocked swiss dot that we commonly see) and I can't even find the sold link to it.
Google Image search and reverse image searches have turned up little to nothing, so I went with this back up woven cotton that's already in a close color that I found through Etsy. The dots are a little too close, but they're not flocked and they're woven into the fabric like her's is.
The costume designer said that her fabric was a vintage bolt that they had to 3D Print replicate for her stunt double.
The costumes for this show were definitely all over the place and sourced out to multiple places. You'd think all the trimmings and such would be expensive, but I don't think I paid over $30 for all of her trimmings.
