The detached wrists are also ruffled at the cuffs and decorated with gold thread. Her orange undershorts are showing, which are lacy at the edges. She has loose-fitting stockings and high-heeled shoes. She wears a white choker and a stone on a long string, and wields the Rapier. In some concept art she is also wearing a blue-jeweled choker and blue flowers in her hair.
Calista also wears her blue dress in other concept art. The dress is in varying shades of blue, and the hemline goes down as far as her knees. She wears knee-high brown boots.
