My ideas for the alternate costumes is her normal jacket,

her other dress,

a Nepgear outfit,

a Purple Heart color palette (different color jacket, hair, and eyes),

a blue color palette (she represents SEGA),

a dark and red palette (referencing Noire and Black Heart),

a bright and brown pallete (referencing Blanc and White Heart),

and a green and yellow palette (referencing Vert and Green Heart).

All of these are shown on the second picture.
