Best royal fashion this month - including an unexpectedly daring leg-baring look

Zara Tindall was summer chic personified at the Out-Sourcing Inc. Royal Windsor Cup Final polo match and a carriage driving display by the British Driving Society at Guards Polo Club, Smith's Lawn in Egham.

Braving the heatwave, the royal rocked a striped shirt dress by Ralph Lauren with a straw boater hat, block heels by Tommy Hilfiger, and Aspinal of London's 'Lottie' bag.

Queen Mary of Denmark was a human Barbie at the opening of the 'Kongebarn', translated as 'royal child' exhibition. She exuded chic in a lace pink dress by ME + EM with a fluted skirt. It was paired with Valentino slingbacks.

Duchess Sophie rocked day two of Royal Ascot in a bespoke Suzannah London floral skirt and puff-sleeved top. The ensemble was tied together with a magenta Jane Taylor hat and Emmy London's 'Charlotte' pumps.

Princess Beatrice looked blonder than ever while sporting a pink and white gingham skirt and blouse by Beulah London on day one of Royal Ascot. She accessorised with capped-toe Jennifer Chamandi heels and a hat by Juliette Millinery.

Zara Tindall was among the best dressed on day one of Royal Ascot. She could have been Cinderella in a gorgeous sky blue Rebecca Vallance dress with powder pink Emmy London heels and a Sarah Cant hat.

Princess Charlene was radiant in cornflower blue as she attended the closing ceremony of the 64th Monte-Carlo Television Festival. Her Louis Vuitton gown featured a figure-skimming cut and halterneck top.

Kate looked magnificent on Garter Day. The royal was seen outside St George's Chapel in the grounds of Windsor Castle wearing her white lace and boucle midi dress by Self-Portrait with a pair of biscuit-hued Gianvito Rossi heels.

Her look was rounded off with three strings of pearls and a Strathberry clutch.

Sophie got the same stylish memo, arriving at St George's Chapel in the Suzannah London 'Fontaine' dress – a wrap style with a floaty skirt. Her ballet pink look was elevated with the 'Charlotte' pumps by Emmy London and a beautiful hat by Jane Taylor.

Adding an unexpected twist to the look was her frosty 90s eyeshadow, though her rose-toned lip was her go-to shade.

Princess Charlene of Monaco oozed cool at the inauguration of the 6th Meeting of the Historic Sites of Monaco. Rocking the 'Elliot' dress by Diane von Furstenberg, Charlene looked statuesque, the belted waist adding a feminine touch to the maxi dress. The royal seemed to wear flats, though her shoes were hidden under her dress. 

Queen Mary was the royal sporting the most daring leg-baring look of the month so far! The Australian-born Danish royal wowed in a pair of culottes, looked sleek and modern in the bottoms by Mark Kenly Domino Tan for the Global Fashion Summit.

The cut-off trousers were paired with killer suede heels and the matching wrap-style jacket. She further cinched her silhouette with a raffia belt.

Princess Eugenie epitomised summer style when she joined forces with Prince Albert of Monaco at the Thirty Six For Coral – an art exhibition and auction dedicated to coral reef conservation. The royal looked lovely in a halterneck sun dress covered in blue flowers.

The 'Orchid Blues Midi Dress' by Rebecca Vallance was paired with peep-toe heeled mules, and her brunette hair was pulled back off her face.
