We (my wife and me) weren't able to get tickets in time. I can't order them online as I have no credit card. Next time maybe.
If we had gone we would have been dressed goth (as usually) anyway.
I don't really know if there are this many "steampunks" in Belgium. Looking at the reaction here....

?
I don't always dress steampunk, just love tarting around in big outfits of all styles!

However, after attending one of Viona's events before and seeing all the beautiful pompadour/baroque dresses, I know there is no way I could compete with that style so instead am going for a slightly steampunk victoriana look.
I get the impression that the steampunk scene is more spread out in Europe, early days yet, I suppose!!
