Kate Middleton stuns in dress worth this much as she frolics with Charlotte and George

Kate Middleton and her two children appeared to enjoy a family day out yesterday at the Maserati Royal Charity Polo Trophy at the Beaufort Polo Club.

Kate attended the popular royal part time and was seen running around with Prince George and Princess Charlotte.

The Duchess of Cambridge looked stunning in a summer ensemble and a dress with a surprising price tag.

She wore a £39.99 Zara off-the-shoulder cotton and linen blend dress dress.

The dress has a low neckline and showed off the sporty Duchess’s shoulders.

The blue dress had pretty white pin stripes and buttons down the front.

It also had a tie around the waist.

Kate paired the dress with a pair of Russell & Bromley Coco-Nut espadrille wedges.

The shoes cost £125 from the British high street brand.

She re-wore the Victoria Beckham Quincy Leather Tote Bag, which she wore to Wimbledon in July 2016.

The dress can be bought for £517.62 used from Vestiaire Collective UK.

The pretty dress showed off Kate’s post-baby figure.

The slim royal gave birth only two months ago.

Kate Middleton wore a blue dress on Saturday to appear on the Buckingham Palace balcony as part of the Queen’s birthday celebrations. 

Kate’s square neck blue dress was a creation by British designer Alexander McQueen.

McQueen is a favourite designer of the Duchess of Cambridge, who also opted to wear a pale yellow dress by the designer for the recent royal wedding of Meghan Markle and Prince Harry.

Kate wore a matching fascinator style hat by milliner Juliette Botterill.

Kate Middleton’s sister Pippa Middleton is pregnant. 

She is currently 12 weeks into her pregnancy.

What will her and husband James Matthews name their first baby?
