Lauren helped design this costume. No store bought costumes for this girly. The black shirt is a Simplicity pattern: 4301 That's so Raven made from black gauze with sequins. The pants I used a basic pant pattern and added elastic and lace. The black and white fabric from Joann's was difficult to work with...I think it was an acetate that shreds easily. The corset is royal blue stretch velvet made from Simplicity 9836. Stretch velvet and Grommets don't work well even with an interfacing but I loved the fabric.
