Greg's coat is a combination of a (highly modified) simplicity 2333 for the coat and simplicity 5840 for the hood. In order to fit comfortably together, we removed the collar and lapels from the coat and changed it to have a center front opening.
He made his own mask -- it is composed of two layers of craft foam, a muslin backing and held together with rivets and waxed thread. He used the lenses from welding goggles for the eyes and sneaky air holes on the bottom.
The pattern is his own design, based on a combination of tutorials online and images he's seen. It was a fairly entertaining evening as he tried various ideas and wandered around with a giant cardboard beak.
My costume is actually a civil war era shift - simplicity 1139. I'm aware its 400 years off - but, I had it (the pattern, not the shift) and I figured no one would actually notice. (Besides -- how much did shifts really change?) Anyhow, it is SUPER comfy... so I might see if I can dye it, wear it with a belt and work it into my regular wardrobe.
