Solange Knowles is the ultimate chic hipster, so it makes sense that the Brooklyn fashionista be the face of Madewell.

The soul songstress stars the fall ad campaign called "Mix Well. Madewell." The 26-year-old sported boyfriend jeans and cardigans mix and matching laid back, girly, and preppy styles. Solange, who usually rocks cool Afrocentric hairstyles, opted for a large fluffy curly 'do the shoot. Her makeup was clean and simple, donning a faded orangey pink pout and minimal eye shadow. Madewell found the starlet to be its perfect choice. "Solange's great style mix-matched perfectly with Madewell's aesthetic.," said the company.
