Mysterious Dark Skirt
A royal blue mini-skirt made from the top's fabric and trim with black ruffled strips. The waistband is black with a gold stud design at each corner, and hanging from it are two silver chains, one made from beads with small accent charms, the other links. Hanging from the back are multiple pieces of checkered fabric.
Mysterious Dark Boots
Tall black boots with a purple sole and pointed heel. On the foot's corner are silver studs, while pale grey fleur de lis' are drawn on the sides of the leg. The middle has white fabric for the left boot, and royal blue for the right, each with a black ribbon tied over it and silver lining. Black ruffles trim the top of each boot. Two purple straps hang mid-leg on the left boot.
