In 2010, five brand stores were opened in The Netherlands (Utrecht – The Hague – Laren – Maastricht – Eindhoven), one in Ibiza and several shop-in-shops. Additionally, an Amsterdam and Rotterdam Brand Store opened its doors in 2011. In 2012 the label expanded internationally, opening up a store and Headquarters on London's Carnaby Street and New York's Prince Street. In total there are now 15 brand stores internationally, including Antwerp, Gent and Wijnegem in Belgium. The brand also introduced its new label ST. Girls in 2012 to fashionably dress 6-16-year olds. SuperTrash has also launched its own fragrance, Phenomenal and a range of nail polishes. In 2013 SuperTrash has evolved into a lifestyle brand instead of primarily a fashion label.
