Steampunk is an alternative world conceptually akin to Jules Vern.  Lots of gadgets and alternative technologies.  A few years ago, steampunk costumes were scarce at Dickens on the Strand, but over the past couple of years, they have really caught on.  Now, it seems like there were probably more steampunk themed costumes than any of the others.

Lots of leather and strange accessories adorn these costumes.

This couple was dressed all up.  Too bad they didn’t have anything for the child.

This guy was demonstrating his own flying machine.

And, sometimes, steampunk and pirates co-mingled.
