Ghouls! I Need Your Help Figuring Out These Costumes!

Ghouls! I need your help figuring out these costumes!

I need as many fresh references as possible to these 2 outfits so I can start recreating a *version* of them for my partner and I for July.

I gather these are some fairly basic Skeletons, and what appears to be an Edwardian/Victorian top hat on the ghoul. I freaking love the bat/butterfly (batterfly) wings on the ghoulette.

(I'm sorry, I'm terrible and didn't Reaserch band lore. That will change.) Are these the normal Ghoul masks, or are these new iterations?

Being larger and apron bellied, I'll probably wear a skirt or something sheer over my bodsuit to feel less. . . . Bodily.

Greatful for suggestions for Hotfix gems and how to build the Ghoulette's hat?
