Mint Fantôme

https://civitai.com/models/378336?modelVersionId=428444

Sailor: mint fantome (sailor)

Frilly: mint fantome (frilly)

The tokens above alone should be enough. To help with correctness, you can still add additional tags:

General: white hair, gradient hair, blue eyes

Sailor: corset, paw pose, ghost hair ornament, hair ribbon, black ribbon, blue ribbon, ahoge

Frilly: frilly, maid headdress, sleeves past fingers, cross hair ornament, two side up

Additional notes:

Sometimes produces ghosts unprompted

The bridal garter'ed legs in the frilly outfit barely work, there's not a lot of artwork with her legs in it that I could find
