With Charlotte Casiraghi in attendance alongside Princesses Beatrice and Eugenie, the Issa runway presentation had something other shows couldn’t boast: a truly royal following. The Monegasque society beauty joined the Queen’s granddaughters in the front row of the show for the Brazilian label first made popular by Kate Middleton.

With London Fashion Week in full swing, the Duchess of York’s daughters have thrown themselves into the round of parties and glamorous dos. On Wednesday they attended Naomi Campbell’s charity show, and a day later they were again rubbing shoulders with the supermodel.

The fiery catwalk beauty was the surprise signing for the Issa show’s finale, sashaying out in one of the maxi-style tunics that made up the bulk of the collection. Slashed to the waist and accessorised with chunky costume jewellery, the dress is sure to become the signature look for the Euro jet set next summer.
