Solange Knowles at the 2012 Met Gala Ball – Her Dress, Her Style and Her Hair. Solange took our breath away with her high fashion style at last night’s event. She has really grown into a full fashion diva, and her hair is beyond perfection. I love it when a woman can wear her hair as an accessory like Solange does. She was spotted wearing this season’s hottest dress style….peplum. Her yellow floor-length peplum dress was designed by Rachel Roy, and was the perfect complement to her honey brown complexion.To further emphasis her yellow gown, she paired the look with gold accessories, including gold rings, a bracelets and sequined gold clutch bag. Love her look!
