I managed to finish our costumes before the party we attended! It was in quite the mad dash though, at five I still hadn't attached the sleeves! But we did managed to make it to the party on time, and had a blast. Check out these horribly embarrassing photos of me to prove it.
The dress itself is a heavily modified laurel pattern. I drafted the collar myself and just added bias binding on the sleeves instead of drafting cuffs. The fabric is a poly blend suiting, with a very subtle herringbone pattern. I think I'm going to put a tutorial up soon on how to draft and attache a collar, I found a rather neat trick that doesn't involve traditional facings!
