The SuperTrash brand specializes in dresses, tops and pants. A shoe line was added to the collection in 2009, featuring primarily high-heeled shoes supplemented by glamorous flats. Later that year a denim collection named STenim was launched. In 2010, five brand stores were opened in The Netherlands (in Utrecht, The Hague, Laren, Maastricht and Eindhoven), one in Ibiza and several shop-in-shops. Additionally, brand stores in Amsterdam and Rotterdam opened 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 (permanently closed). 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- to 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.
