Just hours after welcoming a second son to her royal brood just this morning, Duchess Kate Middleton left St. Mary鈥檚 Hospital looking like the picture of elegance.

The new mother of three, 36, was radiant in a bright red Jenny Packham dress with a lace Peter Pan collar and nude Gianvito Rossi pumps.

While it鈥檚 unclear if it was intentional, the look was nearly identical to one Princess Diana herself wore while introducing Prince Harry to the world back in 1984.

Duchess Kate once again tapped her go-to designer for her latest appearance. She wore Jenny Packham several times throughout this pregnancy and chose the British designers blue polka-dot dress while leaving the hospital with Prince George, a choice similar to Princess Di鈥檚 green dotted design when debuting Prince William in 1982.

For daughter Princess Charlotte鈥檚 birth two years later, she turned to Jenny Packham again for a blooming yellow floral frock paired with Stuart Weitzman heels.
