Startseite » Company » MARC O’POLO MARC O’POLO Modern Casual. The Modern Casual collection is the main MARC O’POLO collection; our identity, roots and philosophy are represented through it. Since its founding in 1967, our Modern Casual collection has developed towards an urban style with a clean, sophisticated and contemporary look that is balanced by effortless, soft silhouettes and comfortable materials. To this day, we follow our founders’ preference for natural materials, in the summer of through the usage of cotton, linen and silk mixes, in the Winter with styles made of high quality wool and advanced knitwear designs. In alignment with our urban casual style, our color schemes are never loud, but rather, reduced to natural tones and clear contrasts.
