BUILD YOUR OWN DRAGON!!! Whether you're a fan of Anne McCaffrey or George R. R. Martin, you need a little dragon on your shoulder. This one is fairly simply made using a wire armature, foil, tape and some other odds and ends. This was my first attempt at this sort of thing and I can tell you it's easier than it looks to get a great effect.
Search for “DIY costumes” on Pinterest, and a lot of unique ideas will come up – but so will a lot of repeated ideas. One of the most popular costumes online seems to be a deer, which I have figured out because I literally can’t search for Halloween costumes on Pinterest without seeing at least one image of a girl in deer makeup. This isn’t an issue, exactly, because deer makeup is adorable and pretty and fairly easy to do on your own.
