Happy 29th birthday, Solange Knowles! Beyoncé's sis has become a style icon in her own right, which is why there is no day better than today to run down the list of her best looks?ever. We still covet the iridescent, marigold-hued Emilio Pucci column gown she wore to the 2013 Vanity Fair Oscar Party?and have an equal love for the slim-fitting Calvin Klein Collection number she donned at the 2014 CFDA Fashion Awards. Also, it's obvious: Solange loves her some Stéphane Rolland Couture (the couturier responsible for a few of her head-turning wedding day looks). Most recently, she's stepped out in a cream-colored one-shoulder frock from the designer, but we're still reeling from the feathered Rolland confection she wore to the 2013 Cannes Film Festival opening ceremony.
