For her dress look up prompts used in the grid, note the negative aswell cause she has one image with a ribbon on the dress. Might not require all the tags used if you wanna save space for some reason - up to experimentation. Had issues getting the dress to be white until I raised "white dress" to 1.1, didn't test her hair bow but probably similar case.

EDIT: seems civitAI nuked a couple of the grids, so im just gonna paste the prompt here
solo, Ootori Hanae, brown hair, twintails, black eyes, (white dress:1.1), frilled dress, ascot, gothic lolita, long sleeves, puffy sleeves, hair flower, hair bow, walking, city, street lamp, smug
Negative prompt: (worst quality, low quality:1.4), ribbon choker
