Unlike regular folk, Duchess Camilla and Prince Charles aren't able to slip into super-casual, summer attire to stay cool, so they need to find clever ways to stop themselves from overheating. The Duchess has been wearing long, floaty dresses, while Prince Charles is as sharp as ever in suits and shirts.

That being said, the Duchess of Cornwall has obviously been taking heatwave tips from daughter-in-law Duchess Kate, as the 75-year-old has been spotted carrying a sun parasol to protect her from the rays – and the Duchess of Cambridge has used one on public engagements in the past.
The Duchess of Cornwall joked she was going to "take off like Mary Poppins" as she clutched the parasol to protect against the sun.
Luckily for the royals, the temperature in Cornwall was around 28 degrees, 10 degrees lower than in London, with Camilla telling locals: "This is very cool here. It's stifling in London," before explaining: "I'm using my parasol."

The shop's owner said: "I showed them our selection and they wanted vanilla with Cornish buttercream in one pot with two spoons."
