What SiNN does

SiNN GmbH is a privately-held German multi-brand fashion retailer headquartered in Hagen, Germany (Handelsregister HRB 9225), founded in 1850 as a haberdashery and now operating over 30 physical fashion houses ("Modehäuser") across Germany, including cities such as Aachen, Bielefeld, Bonn, Dresden, Hamburg, Kassel, Mainz, Mönchengladbach, Oberhausen, and Wesel. The company sells branded fashion apparel, lingerie, accessories, and travel gear from a portfolio of international labels including BRAX, Marc O'Polo, Bugatti, Tommy Hilfiger, MEY, Gardeur, Roy Robson, and Samsonite, serving women, men, children, plus-size (sizes 42–54), and special-occasion customers. SiNN emphasizes in-person style consultation across its physical footprint, supplemented by an e-commerce website (siNN.com), a mobile app with digital customer card, and tiered bonus coupons through the SiNN+ loyalty program. Supporting services include alteration via partner tailors, article reservation for up to three days, gift voucher cards, and a style guide editorial platform. Revenue is generated primarily through one-time retail transactions (in-store and online), with a modest recurring element via the loyalty program's repeat-purchase incentive mechanics. The company operates with three managing directors (Dr. Isabella Goebel, Christian Döscher, Philipp Reifferscheid) and a regional store-management structure across its locations.
