Dakota Johnson just took the little black dress game to a whole new level! She hit up a swanky NYC party in a sleek Ferragamo LBD, but the real showstopper? A $25,500 Roberto Coin cocktail ring dripping with sapphires and diamonds. It’s the same ring Leslie Mann rocked at the Oscars! Dakota’s now the face of Roberto Coin, so expect even more jaw-dropping jewels in her next red carpet looks. Obsessed yet? #DakotaJohnson #LBD #RobertoCoin #Beauty
