Rihanna knows how to show up to the Met Gala extra fashionably late. This year, Rihanna and A$AP shone bright like diamonds on the red carpet as the most iconic duo in Valentino and Gucci, respectively. Rihanna made her way up the steps in her immaculate white Valentino bridal dress adorned with camellia flowers and a five-foot train. "It's Valentino, baby," she said to the cameras. Meanwhile, A$AP Rocky wore a complete Gucci outfit featuring a kilt inspired by Karl himself, which fell short in comparison, but it was on theme.
