Here it is! Early office Halloween party!
I used a pattern in this Japanese book for the dress, and based the hat on a free fleece hat pattern I found online. Everything went smoothly except for them ears. It took me a while to come up with an idea and engineer a wire-frame and forcefully sew it in, between the exterior and lining. Good thing I used fleece (felt would have worked even better)!
Yes, I have long hair so I braided them up, folded in half and tied it near the base.
And of course, had to take a photo with my co-worker dressed as Tina!
