I'm playing Lyra in the Ardgour readthrough of Northen Lights! It's the best thing in the world.
But I don't have a firm idea about costume yet... what are other people doing (esp. Mrs Coulter and Lord Asrail?)? Are we going for a very precise victorian/steam-punk/replica of the film type era? At the moment I think the best I can do is contemporary urchin, but I want to be inspired!
So, err, even if you're nothing to do with Ardgour but you have a clear mental image of Lyra then discuss it here, because it will be a great help!
