I made this costume super quickly for Matsuricon 2014.

Shirt: Made from black & white stretch jersey knit. Symbol put on with transfer paper.

Skirt: Thrifted the base. Cut a slit in it and sewed line of black jersey knit underneath. Hand sewed the buttons on. The pockets of the skirt actually showed through, because they were above the slip. To fix this I seam-ripped the slip and moved the fabric above the pockets.
