I went as Jock to a big Halloween Party in Chicago Saturday night. There were about 700 people there but unfortunately I think it was a bit too obscure for this crowd. I will post a better photo later but I would have thought that at least the guy in this photo would not need a hint (but he did). I think it is better suited for a convention crowd.
Although you can't see it in this pic, I did iron the words AIR PIRATES on the back of my shirt as well as the JOCK name tag on the front. The hardest part was finding the "reed" fishing pole which I eventually stumbled upon.
Here are a few more pics. In the end there is not a lot to the costume. But I guess that's the way I like mine to be. Authentic looking yet simple and easy to move around in!
