These I found on the Rue St Honore. I wish I hadn't lost the man's card. It was a great shop. It was towards the intersection with the Place Vendome. We have been doing shirts with this kind of detail for some time, although we run the contrast band closer to the cuff edge, not set back.
The quality of fabrication on these shirts was very intricate, even finer than ours, which was why I wanted to photograph them. I would not advocate wearing the silk one second from the top unless you owned a business in the sex industry, but I would definitely consider the top navy shirt for anything seafaring. Joel Varjaques and Marol were just two brands being offered amongst other brands such as Brioni.
