Earlier this week Vogue editor-in-chief Edward Enninful hosted a private afternoon tea party to honour Oprah Winfrey and celebrate her role in A Wrinkle in Time. Guests included Ava DuVernay, Idris Elba *swoon*, Reese Witherspoon and Chimamanda Ngozi Adichie who looked incredibly gorgeous in a statement shift dress by Nigerian brand Idma-Nof. Rather than opting for the obvious, black heels, our favourite author instead chose polka dots which complemented the dress perfectly. Something about the clashing prints just works…the outfit is striking, classy and worthy of best dressed of the week.
