Martina Grasselli has worked in Milan for important fashion brands such as Jean Paul Gaultier and Christian Louboutin. Launched in 2009, as a costume jewellery brand, Coliac soon included footwear too. In 2013 the designer presented her first shoe collection, reinventing the classic brogue with jewellery-inspired details. Crafted to the highest quality, Coliac design preserves the jewellery influence, with studs, pearls, piercing and metallic ring embellishments.
