Steampunk is a new subculture, built around an alternate Victorian era. Main features are earth-tone clothes 100 years out of style, brass and copper and goggles. Lots of goggles.
Steampunk is a new subculture which started in the late 1990's. It emerged, as some say, from the Goth subculture when some of the goths decided that sitting in dark rooms writeing sad poetry was a bit depressing. So they left, exchanged their black for brown, velvet for leather and silver for brass, and the emo for lightning generators. And thus, Steampunk was born. Their patron saint is Nikola Tesla.
Steampunkers are well known for their design astetic, sometimes described as Victorian though a modern lens. They are also known for haveing a huge "maker" mentality, in that some beleive that making your clothes is the only way to go about it. While many do build and sew their own outfits, there are places that are begining to cater to Steampunk fashion.
