EXCLUSIVE AT NET-A-PORTER. Ever since the Duchess of Cambridge wore Emilia Wickstead's 'Aurora' midi dress to the RHS Wisley Back to Nature festival last year it's consistently sold out, so you'll want to snap up this exclusive style now. Cut from Swiss-dot cotton-seersucker, it's decorated with a ditzy floral print and belted at the waist to cinch the flattering A-line silhouette. Shown here with: [The Sant Tote id1229131], [The Attico Pumps id1234181].
