These three ladies have us green with envy. Literally. Miley piqued our interest in emerald late last year when she appeared at New York’s Annual Night of Stars in a Marc Jacobs maxi, and Beyoncé and Lupita have turned our interest into a full-blown obsession this awards season. If you don’t have a Dior couture gown at your disposal, get a splash of mermaid into your everyday look with sparkly drop earrings, unique peg pants or an embellished clutch.
