Solange Knowles could have languished in the shadows of her more famous older sister, desperately trying to emulate Beyoncé, but instead she beat her own path, a gloriously fashionable one, full of fresh yellow, cool separates and surprising pops of brightly coloured accessories. She's the more fashion-forward of the Knowles, a fun, young upstart who is always occasion-appropriate. She stopped straightening her hair back in the Noughties and she consistently wears looks that are somehow laid-back, modern, luxe and free-spirited all at once.
