You can click on the pictures to enlarge them. Sorry for the bad picture quality, I intend to take some better shots with the dress once I get home. If you're making an Elphaba dress yourself, please feel free to write to me and ask me how I did it!
I used many different patterns for the different parts of the dress, but I modified most of them. For most of the bodice and the hat I used the Wizard of Oz pattern from simplicity, I made the pattern for the sleeves myself, Used a McCalls pattern for the corset (the one with the white civil war corset and the hoop petticoat), and a pattern from a 1902 skirt.
Corset front and back. I made the corset part separate from the rest of the dress.
The leaf desing in the front is all hand beaded. There is also some beading on the left sleeve.
I used a green water-based makeup that I found at Sephora. It was quite expensive, but worked like a charm and didn't stain my dress!
