Most women would undoubtedly love the opportunity to have access to the British royals' closets, especially Kate Middleton's, whose always classic and feminine style proves particularly alluring. Good news for all of us: Thanks to her latest red carpet look, it just became that much more doable to play dress up like a royal for a night. The Duchess of Cambridge stepped out for the premiere of A Street Cat Named Bob in a dress brand we all know and love, Self-Portrait! The piece in question is very typical of the brand's ladylike aesthetic—a long-sleeve lace top paired with a fluttery pleated skirt and a thigh-high slit. Of course, her particular dress sold out immediately. Don't worry, though. The brand still has plenty of similar styles in stock, all available at similarly reasonable prices for such beautiful floor-length gowns. Voilà! You're ready to re-create the duchess's style for your next formal event.
