The Duchess of Cambridge looked resplendent as she joined forces with The Countess of Wessex tonight for the Commonwealth Fashion Exchange reception at Buckingham Palace. A first joint royal engagement that has been hosted by the ladies.

Also in attendance this evening was Vogue Editor-in-Chief, Anna Wintour, and Princess Beatrice, both also wearing Erdem pieces.

For tonight’s event The Duchess choose to wear a bespoke piece by Erdem, one of her favourite designers. Kate’s dress is based from the Suzi Dress Guipere Lace Style.

The dress is made from black and white floral guipure lace; it features a deep v-neckline and 3/4 flared sleeves with scallop edging. The original dress nips in at the waist and is in a fit and flare skirt silhouette. It is created from polyester and has nude crepe de chine lining.

The shortened version of the dress retails for at £2,150 at Erdem online, though we have a slight suspicion Kate’s would be worth a little bit more than this, as it was bespoke. The Duchess had her dress slightly modified for her pregnancy with extra fabric added to the hem of the dress to create a midi or tea-length style dress. The hem appears to have a slightly fluted appearance.

The ‘Suzi’ dress was also available in yellow as apart of Erdem Pre-Spring 2017 Collection.

The Duchess choose to wear her Prada ‘Wave cut out pumps’ in black suede. She also wore these very same shoes to the BAFTA’s last night.

Kate’s earrings were her Anita Dongre pearl drops, seen first last year. They were a custom piece, similar to these, but the top stones are larger and more irregular in shape.
