The mum of three chose an understated but fashionable outfit for the occasion, teaming a Reiss beige double-breasted blazer with a simple white top and navy blue trousers.
She accessorised her ensemble with a matching beige mini handbag from British leather goods brand Tusting, a navy belt and navy suede heels.
Relaxed tailoring is a major trend right now and with her slightly oversized jacket and wide-leg trousers Kate nailed the look.
For years, if the 39-year-old was seen in trousers they were usually skinny jeans, but recently she’s ditched the skinnies in favour of on-trend straight leg styles – and judging by the comments, online fans approve of the fashion-forward look.
“I can’t cope with how cute The Duchess of Cambridge is!” wrote Twitter user Kayla Adams. “I said I wanted a blazer moment and she delivered!”
“My girl is back looking all fresh and elegant,” commented another user.
