Just like Estitchy, my shirt wardrobe mostly consists of light blue and blue stripes. I do own a few shirts with black/grey graph checks though, and one tattersall shirt. I need to stack up on tattersalls though, they are the ultimate tweed shirts IMHO.
Followed me too, that's how I found it. I think wearing this would probably attract all the wrong kind of attention to oneself. My mind is just boggled as to how someone thought this up, and then actually followed the idea through as a business venture.
