Everyone agreed she looked breathtaking in her custom mustard yellow Stella McCartney dress, and she has since topped best dressed lists and become a bit of a fashion inspiration for those looking to brighten up a formal occasion.
No doubt her bespoke gown and stylish gold and perspex Gianvito Rossi heels would cost a mere mortal more than a few month's wages, but the actual cost of her outfit totted up by one report could give you quite a shock - if you didn't know what it was mostly made up of!
According to Pricetagged by Page 6, the entire outfit cost more than $500K. However it wasn't the dress that is said to be the most expensive piece worn by the wife of George Clooney - it was in fact the accessories that cost the most overall.
The estimated breakdown follows: Gianvito Rossi shoes: $800; Stephen Jones hat: $335; Stella McCartney dress: 'Priceless'; Lorraine Schwartz earrings: $500,000.
Worth every penny!
