Three costumes, now: Shock from Nightmare Before Christmas, Young Maleficent, and Elsa from Frozen.
The preschooler won't put up with anything uncomfortable and she made me so relieved when she picked a store costume. I knit a hat and added a yarn braid to it to keep her warm. She wore her coat and pants underneath.
Shock's costume, well...didn't work so well. I accidentally made the hat too narrow for her head, so she couldn't wear it outside in the 20-30 mph wind. The mask is model magic with paper mâché overtop, then painted. The robes were simple.
Maleficent, oh Maleficent. First my beautiful intricate, PERFECT horns were too darn heavy. That took me a week of work. So I got made and twisted some foil over a headband and tossed black duct tape over then. Much lighter for a 6 year old. The wings? I thought I told my kids NEVER AGAIN after the Weeping Angel wings but I was suckered into it this year. We made a wire frame with fabric base (cheap flat sheet), then hot glued like 30 cut fabric feathers on it. Oh, and leather horn wing tips. The wire wasn't strong enough, so I had to add a disguised feather dowel for her to prop up or change wing direction. I repeat, NEVER AGAIN.
The dress was easy. I just traced a simple sleeveless dress shape on the best matching fabric I could find and added a Velcro closure.
