I wear that wool vintage Belgian police officer's uniform whenever I can get away with it. It has many features such as snow cuffs, boot blousing buckles, and backpack straps- it is a suit made to be worked in, every day. And I have a rather... active lifestyle.
However, when the weather is warm I tend towards knickerbockers and knee-socks as I am a wheelman. I wear a vest most of the time too, and those aforementioned striped socks:

Here is a candid shot with my other hat, the rail conductor style:

As for the bike, instructions will be in the next issue of Steampunk. You can see the handlebars under the seat, pointing forwards... not that you need them most of the time.
Seeing as this is a thread for discussion of outfits I invite you to examine these pictures from the Personal Protection thread:


You can see how I banded the collar and hand-stitched the vest out of inner tube (look for the nozzles). I actually found a wolf pelt in the dumpster and stitched some to my vest thinking the animal deserves a more respectful destiny than as a footrug. My jewelry includes a large machine chain link in my ear, a wrench necklace, "victualic gaskets" on my wrist (you can actually read those words), skull (SCUL) ring, and a fake bling bling ring (a funny oxymoron, of course, but bling actually protects you from cobras in the bush because they will spit their venom towards the shiny thinking it is your eyes). The hat is from Camden market and the goggles are from an old Rat rodder in PA. Cane and gun are a bit theatrical, the gun is a ball and cap gun. I also have some kind of Navy mechanic's patch on my arm, I wish I knew what it stood for.
A question for the costumers- What are the costumes for? I am having trouble understanding the distinction between, say, dressing steampunk and going to a steampunk bar as an expression of your lifestyle versus assuming a character and putting on a costume to... do what? Are these costumes from plays?
