Analysis of Google search data reveals that searches for ‘red dress’ exploded 376% across the globe on the 9th of January, the morning after a photo of Kate Middleton in a red, one-shouldered gown by Alexander McQueen was released to commemorate her 40th birthday.

A new finding by printing and photography experts Printique reveals that searches for ‘red dress’ skyrocketed to nearly five times the average volume in one day, an unprecedented spike in people searching for red dresses, according to analysis of Google search data.

The Duchess of Cambridge released two additional, black-and-white photographs for her birthday, in which she is wearing luscious white gowns also by her wedding designer McQueen and pearl and diamond drop earrings which belonged to Princess Diana. The data reveals that searches for ‘pearl drop earrings’ jumped 284% across the world on January the 9th, the day of Kate Middleton’s birthday. Searches for Kate Middleton’s birthday photographer Paolo Roversi also skyrocketed by 1700%.

A spokesperson for Printique commented on the findings:

“These new photographs reveal a side of Kate Middleton we’ve never seen before – unafraid, powerful, and with a hint of wildness to her classic beauty, she looks every inch the future Queen. Paolo Roversi has done an extraordinary job of combining classical, idealised elements of royal photography with striking brushes of colour and boldness, from the blown-out look of Kate Middleton’s mane, to the scarlet of her red McQueen dress in one of the photos. Another black-and-white photo, which features the Duchess of Cambridge in profile, reflects the ethereal, regal quality of the renowned court photographer Cecil Beaton, who captured historic images of Princess Margaret and the Queen Mother, and searches for ‘Cecil Beaton’ also exploded 669% one day after the photos were released. All three photographs already have the feel and weight of history, and will remain iconic images of the monarchy as the centuries progress”.
