I think we are officially the only team without one.
I walked into the team store one day and talked to one of the workers about our need for a alternate team jersey. She told me that we are indeed in the process of developing one. Asked her what the primary color would be and she said she had no idea but if I had to pick I would think it would either be Orange, Black, or Silver.
I was able to find a picture of what it would look like black.
I got these photos from McBeastie on Flickr
As you see these jerseys would have silver or orange pin stripes. The Orange would probably have blue stripes, and silver could have orange or blue stripes.
I apologize for not having more pictures but I do not have the software to be able to design them, if you do please post them on here.
