Solange Knowles, soul performer, model, and younger sister of Grammy Award-winning singer Beyoncé Knowles, is the newest face of Madewell, sister brand of fashion retailer J. Crew.

Admired for her sense of style, the 26-year-old entertainer also served as brand ambassador for Armani Jeans, a union Giorgio Armani described as a perfect match: “Armani Jeans expresses my vision of a young, independent, casual lifestyle with a strong and cool, fashion sensibility,” Armani was quoted as saying in an 2008 issue of British Vogue.

Knowles can be seen in Madewell’s ads beginning next month as well as on the cover of its September 2012 catalog.
