I wanted to create a dark and domineering image. The horns are inspired by Mei from Honkai Impact 3d.
Fabric - leatherette, latex, biflex, etc. Instead of a gradient, you can use fabrics with a blue-purple iridescence on the bodysuit.
Sleeves, skirt, chiffon veil, mesh, tulle. Also, instead of a gradient, you can use fabrics with overflows in several colors.
Crafting on the chest in the form of vertebrae and ribs. You can do it in different ways - craft, rhinestones, leatherette, etc. I tried to find references of different options.
