I carefully considered the designs in Honkai Impact and tried to get into the style of the character so that the Bride Kiana would remain recognizable.
At first I wanted a pure white design, but I still added red elements, it seems to me that it looks more harmonious.
Since almost the whole costume is white, it seems to me that you can use a mix of different fabrics to play on the difference in textures. For example, sleeves and body - biflex or leatherette. Puffy sleeve and bow - satin, jacquard.
I also like the mix of glossy and matte textures.
For veils and transparent inserts on the body - you can use lace and fabric with sequins.
