While one could assume juggling motherhood, a multitude of royal engagements and following protocol on how to dress would make looking stylish tricky, the women of the Royal family make it look easy.
From the careful colour coordination of Queen Elizabeth II and Princess Diana's affinity for Peter Pan collars to Sarah Ferguson's penchant for a patterned skirt and Princess Anne's stylish headscarves, every Royal mum has had her own signature style.
While at the Spanish royal residence in 1987, with Prince Harry and Prince William, Princess Diana nailed laid back holiday dressing in a pale yellow jumpsuit and gold ballet flats.

Princess Anne showed that a royal can look just as great in jeans and a jumper as they do in a skirt suit.
Anne matched her jeans and jumper to her patterned headscarf, with a red roll neck underneath adding a pop of colour to this tonal look.

At the Maserati Royal Charity Polo Trophy last year, Kate made the most of the heatwave and opted for a blue and white striped Zara dress. The Duchess accessorised her look with white espadrilles and a tote bag, which we later saw Prince George stash a slinky in.

Sarah Ferguson's navy and white polka dot skirt is a great, easy-to-wear piece for any occasion. Pictured here with her daughters Princesses Eugenie and Beatrice at the Royal Windsor Horse Show, Fergie paired her ankle-length skirt with a plain white t-shirt and navy jumper worn over her shoulders.

Princess Margaret's coat with leather arms and side panels was a glamorous take on black tie dressing. We love that the buttons on her coat match her daughter's, Lady Sarah Armstrong-Jones.

We loved the colour coordination of the Cambridges on this family outing. Kate's Prussian blue outfit, from the Duchess's go-to bespoke couturier Catherine Walker and Co, toned neatly with Princess Charlotte's dress, hair-clip and shoes, Prince George's shirt and shorts and the Duke's tie.
