And this isn't the first time this has happened, either!!
Kate Middleton is GREAT for business!!
Today, it was the lucky Orla Kiely who saw a boost in sales after the Duchess of Cambridge wore her Birdie wool jacquard shirt dress.
Kate was visiting the children at Rose Hill Primary School to help their self-esteem through art therapy.
And clearly she helped women everywhere with some retail therapy!!
