The fashion on a royal tour should never overshadow the diplomatic mission – but wardrobe planning for something on the scale of the King and Queen’s tour of Australia and Samoa this week will have required months of preparation all the same. 

And yet, alongside all of the carefully coordinated visual messaging, there have been some subtle style updates that have made the couple’s otherwise familiar wardrobes look slightly more au courant.

Take Camilla’s sunglasses, from French eyewear brand Izipizi, best known for its chic off-the-shelf reading glasses. The pale blue “E” style, £40, coordinated nicely with her go-to palette of whites and blues, and she’s worn them on several occasions over the course of the trip. The King’s sunglasses appear to be from the same brand, in a different colourway.

The Queen has switched up her dress formula, too, stepping out in silky tunic and trouser sets by Anna Valentine – one of her go-to couturiers – an elegant formalwear solution in a hot and humid climate that does away with the need to wear tights (a necessity when styling a dress). With it, she carried a mini raffia basket bag from Heidi Klein, a luxury beachwear boutique, an accessory that worked better in the context of an ‘ava ceremony in Samoa’s capital, Apia, than a typical boxy leather handbag style.

“We made that [tunic and trousers] a few years ago,” Valentine tells The Telegraph. “She’s collected them over the years.”
