Pippa Middleton and Sophie, Countess of Wessex, both love this stylish summer shoe

Pippa Middleton has us all envious of her chic pregnancy style - but it's her footwear that we're currently lusting after.

The pregnant sister of the Duchess of Cambridge stepped out in the perfect pair of espadrilles earlier this week during an outing to Wimbledon - and we want a pair!

Keeping cool during the heatwave, Pippa paired a loose-fitting, linen Ralph Lauren midi dress with a pair of black lace-up espadrilles by Penelope Chilvers - and the best news is they're £95.

While it's slightly more than you may usually spend on shoes, they're a timeless classic style that will last in your wardrobe for years to come - and so would make for a great investment.

And what's even better news is that they're also currently still in stock, but you'd better be quick as we predict they won't be around for long.

The 'Low Valencia Espadrilles' are made from the finest cotton, perfect for the hot summer days thanks to their lightweight material and canvas setting.

If you're after something with a bit more height, you'll be pleased to know that the shoes also come with a higher wedge, the 'High Valencia Espadrilles', but they won't cost you any more as they're also priced at £95.

The shoes are part of the brand’s classic series of cotton espadrilles and also come in white, soft lemon and a delicate slate grey/blue.

Pippa is such a fan of the shoes she has been spotted out wearing them twice this week to Wimbledon.

But she isn't the only one who favours the stylish summer shoe - the Countess of Wessex is also a fan and has her own pair in light blue.

Sophie, the wife of Prince Edward, was spotted out in her pair of Penelope Chilvers 'Low Valencia Espadrilles' last month at the Remus Memorial Horse Sanctuary in Ingatestone, Essex.

She teamed her pair with a beautiful, floral Erdem shirt dress.

As a brand Penelope Chilvers is no stranger to the royals, having collaborated with Lady Amelia Windsor on a shoe collection in aid of War Child UK.

The grandaughter of Prince Edward, Duke of Kent - who is first cousin to the Queen - helped to design a three-piece collection, which consisted of a pair of clogs, a belt and some boots which were crafted in a striking pink cowhide.
