This thread is beautiful.
A group of friends and I filmed a Sherlock/ Doctor Who crossover fan film and I got to play Sherlock.
So I have a costume from that, though it was a rather quick pull-together.
I also have Molly Hooper and I'm working on Coat Irene and then I found a white dress that reminds me very much of hers.
My best friend does John sometimes(cool since we have a Sherlock-John dynamic in our friendship already), but mainly she does Moriarty. And a fantastic
Moriarty at that. She has a couple different suits and she can even do the voice. We've had a lot of fun doing AU Molly and Jim scenarios.
