So several years ago I saw Cris Angel's Cirque du Soleil show "Believe" and fell in love with one of the costumes. It's a creepily beautiful doll costume. I used it as the inspiration for my Halloween costume.
Here is the inspiration:
Here's a closeup of my mask:
(I made it using my face and plaster strips. The mask was actually my second attempt. I couldn't get the lips pouty enough. So for the second time I kind of puckered and slightly parted. Then smoothed out the mask with spackle and painted it. To get the drippy eyes, I dipped my brush in colored water, loaded it with water and then touched it where I wanted the drip to be. Once it dried, there was a slight color that I then filled in with paint. The downside of the mask: couldn't really drink unless I lifted up my mask.)
I made pretty much the entire costume -- except for the wig, gloves, leggings and shoes. The corset and the shirt were altered from existing clothing. My hat was made out of a veggie can that I covered with felt and embelished with ribbons and feathers.
Here's a better shot of the skirt:
(Someone dropped mustard on it.)
Incredibly -- there was another girl at the Halloween party that I went to that was inspired by the same doll!
