Solange Knowles, Katy Perry, and Florence Welch all had green on their minds tonight at the 2013 Grammy Awards. Solange chose a beaded emerald gown with structured cap sleeves and a thigh-high slit, finished with contrasting neon spiked Christian Louboutin pumps. Katy wore a mint-colored Gucci gown with a decolletage-revealing keyhole and bejeweled neckline, while Florence sparkled in an emerald-green custom-made Givenchy with a side slit and studs. All different shades of green, all fabulous in their own right. But who wins this style battle?
