She looked great yesterday… but wait until you see Kate in her jeans

She (not to mention the adorable Prince George) wowed yesterday at Queen Elizabeth's birthday celebrations in London.

Yes, there was no denying that the Duchess Of Cambridge, who gave birth to Princess Charlotte on May 2, looked absolutely incredible donning a blue and white floral pattern dress by Catherine Walker.

But earlier today, and decidedly more dressed-down, the 33-year-old really turned heads.

Wearing a striped navy long-sleeved top, navy skinny jeans, and nautical-inspired flats, the Duchess and her husband Prince William attended a charity polo event in Gloucestershire.

​And certainly, a mere six weeks after giving birth, she has regained her pre-pregnancy already.

Kate was kept busy running after an active George, who turns two next month.

The toddler looked stylish, complementing his mother's attire in navy, knee-length shorts, a white collared t-shirt, and a blue buttoned cardigan.

Making it a real family affair, also in attendance at the Beaufort Polo Club soiree was Prince William's cousins Peter and Zara Phillips, who turned up with their respective spouses Autumn Phillips and Mike Tindall, as well as Princes Charles and Harry.

In fact, William, 32, and Harry, 30, even got in on the action, taking to their steeds to take part in a couple of the polo matches – much to the delight of the crowds.

Earlier this week, it was revealed that Kate and Wills have now hired a new housekeeper for their rural abode, Amner Hall.

US Weeky confirms that 33-year-old Sadie Rice, who previously worked for Crown Prince Haakon and his wife Mette-Marit in Oslo, has already taken up her position.

Her duties will include running the house, cleaning silver and glassware, being in charge of household supplies, preparing and cooking meals, taking care of the royal couple's wardrobes, and caring for the family's dog Lupo.
