While promoting Guess in Sydney, Australia as the face of the company's newest campaign, Gigi Hadid wore the brand head to toe, in their Classic Cropped White Denim Jacket ($128), white skinny jeans like the Low-Rise Power Skinny Jeans in Optic White Wash ($148), and snake-patterned Bittan2 D'Orsay pumps ($99). Wearing all white is an easy way to put together a stylish summer ensemble, especially when you accent it with a patterned heel.
