I finally ended this cosplay!
Everything is handmade.
Corset: I used a Mc Call sewing pattern. All beads were sewed on by hand.
White skirt: I used red roses appliques a friend sent me from Sri Lanka. I added beads and sequins to link those red roses to the skirt bottom.
I drew white roses on red fabric and sewed on it transparent miyuki beads to give them more contrast.
Wig: bought on ebay, I restlyled it a little.
Scepter: That was my first cosplay prop I made. More details on my blog: http://www.corycaly.com/blog
Orb: I used a transparent plastic xmas ball and painted it from the inside. I glued a ribbon and sequins.
Crown: I used craftfoam, painted it and added all the decorations.
Rosary: I tried to do it with fimo but it failed miserably. Since I have little time left before the convention, I bought a rosace, a lion pendant and a horse pendant then glued them together. The two swords were made of craftfoam: I glued metal beads on it.
