Camilla, 73, donned a cornflower blue midi dress with black suede knee high boots for tea with representatives from the Royal Osteoporosis Society (ROS), to mark World Osteoporosis Day. The Duchess accessorised with a silver knotted brooch, which appeared to be a sweet tribute to the charity’s logo. Her daytime ensemble drew compliments from royal fans on social media, with one commenting: “The Duchess looks very pretty.” Another said: “This work by the Duchess of Cornwall is a wonderful tribute to her late mother, Mrs. Rosalind Shand.” Camilla has been President of the ROS since 2001 and became involved with the ROS following the deaths of her mother, Rosalind Shand, and grandmother, Sonia Keppel, as a result of the condition. In a moving video message on Monday to mark the charity’s awareness day, the Duchess said: “Today gives us the opportunity to unite, to put the spotlight on the immense global burden caused by osteoporosis. I became involved with osteoporosis 26 years ago, after my mother died as a result of this devastating disease.” “In those darker days, it was seldom discussed, rarely diagnosed and usually attributed to older women, with so-called ‘dowager’s humps’,” she added. Camilla also congratulated Christine Sharp, the new winner of the Duchess of Cornwall Award, during a phone call. The award exists to recognise an individual for their outstanding contribution to the field of osteoporosis.
