Keep everything in the current image unchanged, including the character's face, hairstyle, hair color, eyes, expression, body proportions, pose, hands, gloves, bodice, chest bow, accessories, background, lighting, composition, and overall art style.
Refine only the skirt structure.
The MAIN visible skirt fabric must be WHITE.
The entire outer skirt should be predominantly white, with the same white fabric and delicate frills as the current outer skirt.
The BLUE COLOR must appear ONLY on the INNER SKIRT LINING and the UNDER-SKIRT / INNER PLEATED LAYER beneath the white outer skirt.
Do not make the blue inner layer into a large front-facing skirt panel.
Do not divide the main skirt into white and blue sections.
Do not create a half-blue, half-white skirt.
The blue should be mostly visible along the lower inner edge, beneath the white outer skirt, and slightly between the white pleats when the skirt moves.
The overall visual impression should be:
WHITE outer skirt + BLUE inner lining + BLUE inner ruffles.
The white outer skirt should remain clearly dominant.
The blue should function as a secondary accent color rather than the main skirt fabric.
Preserve the existing blue chest bow, blue hair ribbons, blue accessories, and other blue costume accents.
Do not redesign the costume.
Do not change the character.
Do not change the pose or composition.
