And an eventful return it was indeed.
Following a dramatic failed landing, the parents-to-be slipped into their Friday best for the Australian Geographic Society Gala Awards at the famous Shangri-La hotel. Prince Harry chose a casual suit and tie ensemble for the occasion, while Meghan gave off major princess vibes in a beautiful Oscar de la Renta dress.
The intricate black-and-white tulle gown featured equally-as-beautiful bird embellishments by artist Sarah Esmoingt. She complemented the dress from the famed designer's Pre-Fall 2018 collection with a ring from Maison Birks and Aquazzura pumps.
The internet couldn't handle the gorgeous look, with a Twitter user even calling Meghan a "modern Grace Kelly" in the gown.
Meghan's dress reminds me of a modern day Grace Kelly. I suspect it's the look of the tour. pic.twitter.com/Q6fDaZwMFE
