Princess Eugenie of York and Princess Beatrice of York arrived at Westminster Abbey wearing two gorgeous outfits — a bright blue, floral-printed dress by Vivienne Westwood and a nude A-line dress from Valentino Couture, respectively. Princess Eugenie went for a colorful look, wearing a bold blue dress with a voluminous skirt, flowered jacket, and peacock-feathered hat. She accessorized with bronze pumps and a matching box clutch. Princess Beatrice, on the other hand, opted for a subdued, neutral look — she wore a dusty-pink, A-line belted coat with nude t-strap heels and a very amazing, very Lady Gaga-esque fascinator. Which princess do you think looked the prettiest?
