Alessandra Ambrosio
At the Cannes Film Festival in 2019, Alessandra Ambrosio ravished in a red-hot halter dress by Julien Macdonald. The slinky frock featured a keyhole cutout and looked like it was missing a chunk of fabric on the left side of the leg.

The Victoria's Secret model teamed her dress with strappy gold heels by Giuseppe Zanotti, a gold tassel bracelet, gemstone drop earrings, and a loose center-parted chignon. To finish off, she swiped on some red lipstick that perfectly matched her dress.
