Earlier this month, the Duchess of Cambridge released a stunning new portrait of herself as she shared a look at her Hold Still book, which is out in May.
In the shot, the gorgeous mother-of-three was holding her beloved camera and wore a burgundy red jumper, layered over her ruffle blouse by Sezane. The blouse had a pie-crust neckline - a style that was favoured by her late mother-in-law, Princess Diana.

The blouse in question was a key feature in Princess Diana's wardrobe throughout the 80s - she often teamed hers with a skirt suit, midi skirt or pinstripe trousers - and this is seen vividly in the Caroline Charles outfit she was pictured wearing in 1983, as well as the Jasper Conran suit she opted for in 1981.

Kate's Sezane shirt is sadly a past season-buy, but the classic style is one that has remained a firm favourite in her wardrobe - she first wore the design in 2019 on a trip to the Lake District and has sported it under various jumpers and knits ever since. We've found some lookalikes from the high street - keep scrolling.
