Margot Robbie just gave Us a masterclass in effortless airport dressing, and it all starts with one key piece. The Barbie star proved that this low-key denim detail is the secret to looking polished in transit without trying too hard. It's the kind of outfit that feels equal parts easy, elevated and quietly expensive - exactly the energy we want when we're heading to the airport. According to Vogue, Robbie was spotted strolling through Sydney airport keeping things simple in a relaxed white T-shirt, loose cuffed jeans, Chanel flats, oval sunglasses and a slouchy burgundy bag.
