U2 Clothing was a casual-wear clothing brand founded by Michael Tien in 1980 in Hong Kong. Tien founded G2000 at the same time, with both operating under the G2000 Apparel Limited brand. In 2007, U2, G2000, and a third brand of the same company called UWoman consolidated into a single retail chain retaining the name G2000, which offers the pre-existing product lines under new labels---G2000, G2000 blù (formerly U2), and G2000 Pink (formerly UWoman).
