Each new milestone the Duchess of Cambridge attends translates into huge profits for their fashion lines.
LONDON, ENGLAND (NBC) - England's young Prince George, son of Prince William and Princess Kate, recently celebrated his first birthday.
However, designers across the UK are the ones really celebrating as each new milestone the Duchess of Cambridge attends translates into huge profits for their fashion lines.
They call it "The Kate Effect."
Dress designer Seraphine saw profits quadruple after Kate wore one of the company's creations during a formal family photo in 2013.
According to Seraphine, Kate placed her dress orders just like any regular customer would, with the exception that the delivery address was Kensington Palace.
It's not just dresses, L.K. Bennett's sales soared after it was revealed that the high-end shoe maker was one of Kate's favorite choices for footwear.
And the duchess' Alexander McQueen wedding dress has been replicated for countless brides worldwide.
Renaud says Seraphine's profits have jumped at least 60 percent, a trend that is unlikely to change anytime soon given the high visibility and appealing fashion choices made by the young Duchess of Cambridge.
