I decided to be a knight somewhat randomly this year. I believe I was inspired by some knit chain mail I'd seen here and there on the internet. I wanted it to be girly, but not like a "sexy knight" costume you'd find on a costume web site. It turned out just like I envisioned.
I bought the shiny material at Joann's for half off ($12) and the spray paint for my boots at a hardware store ($8). The chain mail cowl is knit with grey acrylic I had lying around held together with shiny silver embroidery thread ($6). It looked great in the sunlight, but I don't think the shiny really came through indoors. Almost everything else was stuff I had lying around. The blue tunic is made from material from last year's Alice in Wonderland costume. The zipper I had wasn't really long enough so it's challenging to take on and off. My boyfriend got really excited to make my sword. It's made of a dowel (less than a dollar), cardboard and duct tape with bicycle grip tape for the handle. It's incredibly sturdy and good for hitting things.
The shiny pant were made from a tutorial I found here (http://www.craftster.org/forum/index.php?topic=251506.0) on Craftster. They're pretty comfy and I may just start wearing them around. I don't have a great photo of them, but they're leggings made of the shiny material.
Last but not least, the boots. I had planned to make boot covers, but I couldn't get them to look right, so I decided to spray paint my old Docs. They look great, but the paint is still a little tacky and I'm not sure it will every really dry correctly. I suspect that won't stop me though. I love them silver!
I loved being so shiny all day. Most people got it right away, but I did get a couple people guessing spacegirl. A couple mods and next year I could be Major Tom. We'll see!
