Sketch of Rumiko's dress

It's a sketch of the dress I'm going to make for the Arizona Animecon. I'm going to attatch the sleeves to the corsset and the corsset is going to have diamonds on it. Also it's going to be red but I have no idea what to make of the middle. I'm thinking about just doing that white maybe and yes this is a redo of her dress. I decided to make it even beautiful than ever before.
