Bye-bye, basics! With the exception of Julianne Moore's Valentina Kova LBD, this week's best dressed list is all about color, prints and texture.
Kiernan Shipka's floral mini by Mary Katrantzou resembled a technicolor Magic Eye illusion puzzle. Poppy Delevingne took a sophisticated approach to flowers in her gorgeously-fitted Vivienne Westwood Gold frock, while Lupita Nyong'o went for the glitz in a glittering palm tree shift dress by Fausto Puglisi.
And even the white looks weren't spared of extra embellishment: Jessica Biel and Karolina Kurkova sported dresses with three-dimensional appliqués (by Honor and Giambattista Valli, respectively). SJP's floaty Schiaparelli was smattered with pretty pastel polka dots, and the lace covering Allison Williams's Dolce dress took the look from demure to pure sass.
