Pop the champagne! The gents at The Chap journal have set up a shop (here) selling, amongst other things, brogues, trilbys, and cravats. In their own words:
The Chap is constantly being asked such plaintive questions as "Where can I buy a decent trilby?" and "Which shops sell sock suspenders?" We have therefore decided to open a modest little general store for gentlemen. The Chap Shop contains six departments, each serving an essential area of the gentleman's wardrobe. These items are currently only available to residents of the British Isles.
The Chap has painstakingly combed the aisles of the remaining British suppliers of gentleman's necessities, to find what we consider to be the very best items available at the most reasonable prices.
It's a promising enterprise and I for one will drink a celebration toast with a glass of Veuve Cliquot. Best of luck to them.
