My boyfriend and I were really big into Angry Birds when we first started dating. The sorority I am in has a casual Halloween party every year. We wanted something recognizable and creative, but also comfy and not over-the-top. All we did was dress in the color of our bird. Then, I made hats to look like the birds out of felt, feather, and fabric glue. It was super simple, cheap, and reusable. I wear the red tank top all the time!
