I have also begun sewing my costume, a wine-red Arwen style dress, but I certainly won't be wearing that during the daytime! It might be a good idea for those of us who are attending to PM each other for our real names, as I assume most will have those, not nicks, on their badges. I do own one of the Downs T-shirts, but I don't actually wear it, since green does not become me at all.
For those who want to take part in the Costume Extravaganza, it's a good idea to contact the address given in the booklet in advance - they are doing that event in big style, with a catalogue of the costumes, so want pictures by the end of June.
Here's a list of those who are planning to attend, as far as I know - if there are more, please post here to let the rest of us know!
