Pinpointing a specific idea – be it an era, movement or muse – is one of the key ways that celebrity stylists deliver impact.

A red carpet look that can be devoured by the fashion cognoscenti? Practically guaranteed to hit the spot.

One of those who understood the assignment recently at Cannes Film Festival was runway royalty Naomi Campbell.

Styled by Zendaya's go-to "image architect" Law Roach, the supermodel powerhouse made La Croisette her catwalk in a striking piece of Chanel couture, dating back to 1996. The original wearer of the gown? In a display of iconic Naomi behaviour, she took inspiration from herself.

The Extrapolations star styled her romantic dress with a dazzling necklace, prettily opulent but not diverting from the drama of the frills.
