Just as we thought the royals had slipped into hibernation at the end of the summer, Princess Beatrice and Princess Eugenie emerged in all their glittering glory at the Vogue World: London 2023 party.
September also marked a major month in the style stakes for Meghan, the Duchess of Sussex, who was crowned a monochrome maven at the Invictus Games with an expertly packed suitcase of neutral-toned ensembles.
The Princess of Wales has proven her penchant for power dressing by kickstarting her return to royal engagements in an immaculate army of tailored suits, while the Duchess of Edinburgh has equally reigned supreme with her effortlessly flattering fits and feminine flair.
