This is the first series for my new line of Steampunk bras. They all have this same basic shape and details but I make each one sized to fit the individual customer. Some will have a different combination of aluminum, copper, brass and silver. I hand cut each of the gears since I was having such difficulty finding just the right size on a regular basis. I also change up some of the extra cables and fittings a little so that there are no two exactly alike. For sizing details check the link for my fitting site: http:wiki.therobotgroup.org/wiki/BraSizingGuidelines in my profile and shop announcement or contact me for any questions. Also contact me for a quote on shipping outside the USA. Shipping is FREE inside the USA.
