Arriving at legendary sports ground Croke Park, the home of the Gaelic Athletic Association, Meghan swapped out her earth green Roland Mouret dress, worn to meet the Irish President, for a black trouser suit.
The Duchess’s far more relaxed look featured a cropped blazer which she wore over a simple white t-shirt and slim fit trousers.
She accessorised with Sarah Flint heels and a simple black clutch bag.
It’s not the first trouser suit we’ve seen on the Duchess, who famously wore an Alexander McQueen iteration to the Endeavour Fund Awards in February, prior to her wedding.
It’s worth noting that Prince Harry also made a quick outfit change, swapping his formal navy blue suit for a far more casual white shirt, which he wore unbuttoned, with a grey blazer.
