This year some of us decided to go "Steampunk" for Halloween. I don't know if I would say my costume is really authentic Steampunk (which is funny to say since it is a sort of made up time period) but I was pretty happy with the way it turned out. I am supposed to be a Steampunk Entymologist (bug scientist).
We did a little photo shoot at an abandoned building that had a kinda Old West facade. It used to be an antique store, I think, but it's falling apart now. You can see more of my costume here. My mom added the puffed sleeves to my shirt but most everything else I just bought at the thrift store. I made the "cincher" corset-type-thing from a paper bag and gold duct tape.
Here's a better picture of my hat. I made the form out of cardboard and covered it in wrinkly paper bag. Then I painted it, added some faux-leather trim, some packing tape with an insect pattern (found at Target in the office supply section) and some plastic insects I had "antiqued" with black and gold paint.
Below is a picture of my sister's costume, from the back. She's lucky because her hair looks cool without having to wear a wig! Isn't the tree awesome?
Here's a action shot of my brother-in-law above and one of my sister (Ma Barker style) below.
