Northern Irish bridal designer Mary-Rose McGrath whipped up this replica of Sarah Burton's Alexander McQueen design, an incredible 24 hours after the ceremony - which is now available to buy exclusively at House of Fraser.
"I've a really brilliant team," explained Mary-Rose, who's previous designs were already stocked in House of Fraser's Belfast store.
"We gathered together on Friday and the minute Kate stepped out of the car we were sketching and began to cut fabrics."
And at first glance, we've got to admit it's not a bad copy - with similar lace appliqué detailing and full embroidered skirt, complete with train.
But the main difference? While the new Duchess of Cambridge's gown reportedly cost a cool £40,000, this high street copy is available to order from £1,500.
