Steampunk, Goth's more industrial, lighter cousin has drawn inspiration from sources like Jules Verne, fashion designers like Jean Paul Gaultier (think the costumes from "The City of Lost Children"), Amelia Earhart, etc. The NY Times ran a great article on the fast-growing movement recently.
This Saturday, the fantastic Brooklyn Indie market is having a fashion show and selling the wares of the best independent designers. "Victorian refreshments" are promised, as well as themed music and tarot card readings. Admission is free!
