A few guidelines for dressing Steampunk
Steampunk is a sub-genre of science fiction that typically features steam-powered machinery, especially in a setting inspired by industrialized Western civilization during the 19th century. Steampunk works are often set in an alternative history of the 19th century's British Victorian era or American "Wild West", in a post-apocalyptic future during which steam power has regained mainstream use, or in a fantasy world that similarly employs steam power.

Since the Victorians were the first to create steam technology, most steampunk takes place in the Victorian world or inspired by it. You can’t be “too Victorian”, as long as you have created an outfit that is splendid to you and engages others; your style is on track. No need to feel obliged or second-guess yourself into including “steampunk status symbols” (goggles, clock parts or industrial metal objects) if they do not work with the vision you are attempting to produce, go with the less is more rule.
As far as color, there is no “steampunk color.” Some people believe it is only brown, black or only light... Virtually any color can be steampunk. As I drive around my hometown of Buffalo, News York, I am surprised and delighted to see restored Victorian Homes is brilliant colors. Embrace the colorful aspects of this era gone-by. Remember, steampunk is set in a world of comparatively advanced technology, so it is perfectly reasonable to have vibrant colors and complicated machine-made patterns.
You are allowed to like other genres. If you like a style of fashion that does not fit into the industrial age, for example: Mod 60s, you can utilize the mechanical parts of that period. Then it becomes a sister to the steampunk industrial feel but it is not steam punk… all be it cool and expressive. Go ahead and expand, and explore. Be diverse and well-rounded with differing interests. Let that be a source of pride. Have fun and be yourself. That’s what this is about...
