There is so much more to steampunk than dressing up in Victorian style clothing. It is developing in various fields of interest and carving out a signature in music, movies and literature. It can cross a multitude of topics and the boundaries are constantly expanding. Because these boundaries are always being pushed and explored, steampunk is becoming more diverse and varies in a number of fan's imaginations.
One might enjoy the fashion or clothing. Another might enjoy fantasy stories set in Victorian style realms or futuristic alternative Gothic/steampunk worlds. There are also various steampunk style ornaments. I've even seen a lavish looking bathroom complete with toilet and tiling in the wonderful steampunk style.
Steampunk of today appears to be an alliance of Victorian age coupled with science fiction. It seems to have a ruled structure yet an invitation to meddle and redesign while maintaining that old world vision of clothing, steel and rivets.
