Solange Knowles wore Rachel Roy strapless peplum gown, in which she attended with the designer.

Formerly an Armani brand ambassador, the singer-fashionista now models for J. Crew's sister chain.

Madewell has announced the lovely Solange Knowles as its new face for Fall 2012.

Usually hiding in sister Beyonce's shadow, the 26-year-old singer and fashion lover is certainly coming into her own. 

She previously modeled for cosmetics brands, including Rimmel and Carol's Daughte, and was also a brand ambassador for Armani -- no small style shakes there -- back in 2008.

Her celebrity predecessors at the casual wear chain of Madewell include Dree Hemingway, the great granddaughter of Ernest Hemingway, and Alexa Chung, who previously collaborated with the company on two exclusive lines. 

Knowles' quirky style is perfect for the campaign "Mix Well, Madewell."

Check out this behind-the-scenes video that shows a wide range of polka dots, stripes and fun prints from the Fall Season.  And we're loving her fabulous fluffy 'fro!
