Margot has attended Cannes before, albeit just for a day of mixing with others. Back then she wore a simple Manning Cartell dress.

Although I respect the Chanel look from the Spring 2011 Couture Collection was a good throwback, instead of using a current collection, I expected a lot more from her appearance.

For footwear, she wore a pair of Satin cut-out ankle booties from the Chanel Spring 2019 Couture Collection. Thank you @galeyrobbie!

For jewellery, Margot wore a pair of Chanel Panache Earrings from the Plume Collection

Margot wore the Chanel High Jewellery Comète Ring. This is unavailable for sale.
