blue lipstick/nailpolish/cokebottle glasses, in case it’s hard to tell on the sheet. other than that there’s not much else to say, it is a pretty simple costume i think, not a lot of details. it is layered though, it’s that shiny dark corset thing over a dark blue thing over the white shirt.
i’m not sure if the white shirt is actually separate from the skirt or not; it could be a dress too. or the dark part of the corset which is not shiny is part of the skirt and the white shirt is beneath it. idk you will never see her undress in the comic so there isn’t really a correct way to do it, it depends on what would be most comfortable and easy to make. along similar lines her boots look like this but she is not going to show that much leg ever so accuracy doesn’t matter much.
