Kate donned the 'Rubik' coat in the same year during a visit to the charity Action on Addiction in Warminster, Wiltshire. The wrap style has a large high neck and is the perfect statement piece. It looks great on both women - what a pair of style icons!

Kate wore the same style back in 2015, but wore it buttoned up!

James and Alizee married in front of friends and family in Bormes-les-Mimosas, a beautiful village in the Côte d'Azur, in September 2021. Alizee wore a white floor-length gown featuring a Bardot neckline and embroidered detailing, which was the exact dress that James' mother Carole Middleton wore on her big day with Michael 41 years earlier. How wonderful?
