For steampunk-ey items, try using items from the
Phoenix Jubilee 2010 event (commons or rares, it was a very steampunk event).
There are also the
Steampunk Headgear and
Fleet Commander contribution items.
For the more Victorian side, I'd look at the commons from the Shipwreck ball, like the large panniers and colorful corsets. The set looks a bit like this:
That might look a bit luxurious for the theme you're going for, but I think you could probably use one or two items, like maybe a wig or corset.
