...but what IS Steampunk?
Every Steampunk you ask will have their own definition. As it relates to fashion, I generally see it as Victorian-inspired aesthetic with a sci-fi twist (or sometimes a fantastical one).
Most of my Steampunk items listed are NOT similar to garments or accessories that you would have found in Victorian-era homes. Rather, my items include design elements that put me in mind of Victorian fashion or decor, and/or elements of science fiction and industry (i.e. gears or cogs - as the joke goes, "just slap a gear on it and it's Steampunk!").
