The always impeccabily dressed Luca Rubinacci of Rubinacci tailors, Napoli. You can read a little article on Luca and his father, Gennaro, here. I love that Luca isn't afraid of colour: everything just works so perfectly together and most importantly, accents his amazing blue eyes (and they are even better in real life!).
You can find Rubinacci in Mount Street, London, as well as Milan, Napoli, Tokoyo, New York and Rome. I also discovered, with a little googling, that they have an online shop where you can buy accessories such as scarves, pocket handkerchiefs and watches.
