I get great pleasure making collages with materials.
1. For the fabric on the bodysuit, sleeves and stockings, different fabrics
(biflex, leatherette, velvet) may be suitable. I like the option with velvet the most,
if it is also black with a burgundy tint, then it is generally perfect! Unfortunately,
I didn't find a a sample one to insert here, but there probably exists one :D
2. As a decor, leatherette, lace, sequins are suitable.
And it's better all at once :D I attached pictures for inspiration.
3. It can be beads, crystals, pearls. I like all the options.
4. For sleeves and veils, there should be a translucent fabric.
It can also be with sequins or some kind of decor (lace, beads, etc.)
I tried to sketch all the details of the costume in as much detail as possible.
But if you still have questions, be sure to ask me.
