Putting a Knot in Both Ends of the Line
Kate has honed a talent that enables her to make adjustments to her ensemble in the event that something is wrong with it, even before anybody else is aware that there is a problem. The cameras filmed her as she re-knotted the front knot of her dress in order to correct the issue that had arisen when the knot began to unravel.
She was never in risk of being caught because, happily, it did not serve any practical use and was just decorative in nature. This meant that she never had to worry about being discovered. I would suggest, Your Grace, that you err on the side of prudence rather than looking back with regret.
