I managed to find a coat I could use for the Jacket, and I'll keep searching through charity shops as well. I've also worked out how to overcome the issue of breast pockets... that being - there isn't an issue. I can simply decorate around it. It would be better if there wasn't one, but if needs be, it'll have to stay!
If any of you can find a wig that looks closer to the one in the episode - please tell me, either in the Disqus comments to the right, the Weebly comments below, or via the Contact form! Your help would be much appreciated!
