While many of us are still lusting after that gorgeous gold Jenny Packham dress that the Duchess of Cambridge wore to the No Time To Die premier on Tuesday evening.
The duchess was back to her usual, more casual, wardrobe on Wednesday during a visit to the City of Derry Rugby club in Northern Ireland.
Known for championing high street brands, the mum-of-three wore a simple black ensemble, which featured a sporty jacket from popular athleisure brand, Lululemon.
The duchess was joined by the Duke of Cambridge at the rugby club to meet with players, coaches and volunteers involved in the ‘Sport Uniting Communities’ initiative, which is a collaboration between the Irish Football Association, Ulster Gaelic Athletic Association and Ulster Rugby.
The club, based in Londonderry, Northern Ireland, aims to promote peace, and - as is their style - the Cambridge got stuck in with a rugby ball themselves.
For the occasion, the duchess donned the Define Jacket Luon Jacket from Lululemon in black (though it's available in no less than eight different colours), pairing it with black trousers and trainers for a chic, sporty look.
We can't be sure why the jacket caught the royal's eye, but we reckon it might have something to do with the cotton-soft feel, secure front pockets, and the thumbholes which keep the sleeves firmly down and the cold at bay.
It's deceptively warm, flattering and easy to throw on. So, with autumn upon us, it looks like the perfect item to add to our workout wardrobe ASAP - particularly as The Duchess Effect will likely mean the jacket soon sells out.
