The genius of vertical integration is that it draws a direct line from the base product to the consumer, like when a farmer opens a grocery, or a coke dealer opens a disco. For the clothing version, hit Sebastien De Paris.
Run by a 3rd generation fashion scion, SDP started as a family textile business in Europe (they still produce high-end fabrics for Euro designers); however, after years of wistfully gazing at all that beautiful beautiful cloth, they decided to work with in-house designers on their own brand, Atelier Privé. 100% cotton dress shirts come with a variety of collars: the Italian (wider spread for bigger knots), the Classic (a spread, but not as flamboyant), and smaller runs of various narrow and button-down collars that work well with skinny ties and lapels; there're also three silhouette options: Slim, Fashion, and Classic (a gentle euphemism for those whose flamboyance is in their girth). Slacks come in either a (again) classic or more fashion-forward taper, in colors like stone, black, and various grays, all made from the family's flexible, easy-draping nylon, spandex, and Lycra blends, otherwise known as techno-fabric -- elegant enough for a romantic dinner, forgiving enough for a face-melting rave.
SDP's also got a crap-load of ties in a myriad of colors that jive well with the company palate, available in both standard and skinny -- which, if you spend all your time in well-powdered discos, should nicely match you.
