Here's a shot of the jacket done similar to Alan's (thanks to his heads up about the ebay listing)



I have to agree that the jacket being black really makes it difficult ot dress it down to a casual or semi-casual level.

A fe months back however, there was a photo of someone wearing a PC jacket (silver buttons and all) with a standard white button down collared shirt without a tie (or maybe it was a jacobite shirt, I only remember it had a collar and was open at the neck. It looked pretty good but still had a look of "at the end of the reception when everyones hot from dancing".
