Lady Amelia and Lady Eliza Spencer, the twin nieces of Princess Diana, stepped out at the Cannes Film Festival for a joint appearance at the Coward screening on 21 May.

The 33-year-old models later shared a behind the scenes Instagram video (posted 26 May), giving a rare peek into their pre-red-carpet ritual and it was pure Riviera chic.

Filmed on the balcony of their hotel, the sisters looked modern screen sirens, slipping into ethereal, sheer babydoll-inspired dresses layered with delicate lace robes by Bocan in crisp white tones.

The duo leaned into the ever-evolving “naked dress” trend, a red-carpet favourite that continues to dominate 2026 but softened it with romantic, ice-toned elegance. 

Fashion’s ongoing obsession with underwear-as-outerwear was on full display too, a runway narrative seen everywhere from Miu Miu’s layered lingerie styling to Simone Rocha’s sculptural romanticism. 

Sheer mesh, lace, and barely-there fabrics have become the language of modern evening wear.
