Dean and Dan Caten Canadian creative fraternity design duo are identical twin brothers, fashion designers, founders and owners of the DSQUARED². These Toronto native, twin brothers/designers worked under Ports 1961, Versace and Diesel. In 1994 they debuted their wildly popular men’s collection and in 2003 released their women’s line. DSquared2 has created looks for Britney Spears, Madonna, Rihanna, and a football team. It’s no wonder we can’t get enough of these two Canadian brothers and their always cutting edge designs.
