Kate Middleton steps out again! Our favorite royal made her second official appearance this week in a vibrant blue L.K. Bennett sheath dress for the opening of the ICAP Art Room at Northolt High School in Ealing, England. Kate chose a more casual look for the day—compared to her elegant silk-tulle Jenny Packham dress she re-wore for the National Portrait Gallery’s Gala—where she joined students for a quick art session.

The Duchess of Cambridge finished off her look with Kiki McDonough earrings, a gorgeous bouquet of flowers, and of course, her megawatt smile. If you want to scoop up Kate's slim-fitted Detroit frock—priced at $395—you're sadly out of luck, it's already sold out on the designer's e-commerce site just hours after Kate was seen wearing it, but we found this similar version from Adrianna Papell, and it's less than $100.
