Coltrane is a Swiss fashion brand, founded in 2016. Its design approach consists in emphasising the special texture of beautiful natural materials. These materials come from suppliers who work on transparent ecological and sustainable principles. The collection is entirely produced in Switzerland, and relies on the expertise to be found in this country. A network of outstanding tailors and other craftsmen is the guarantee of a constantly high level of quality, and also forms the basis for a flexible response to the demands of the market. Coltrane reaches its international clientele through direct sales by way of the Internet. The only marketing channel it uses regularly is Instagram. Influencers discovered by Coltrane on Instagram have helped make the brand well known. Within just two trading seasons it has succeeded in selling its products on three continents of the world, and in establishing highly promising contacts with first-class international retailers.
