While Princess Charlotte’s shades and sundress at the polo is a look we can most definitely get behind, it’s Kate Middleton’s off-shoulder Zara dress we’re mostly obsessed with right now.

The Duchess does summer casuals like no other, and it's no secret that she's a big fan of everyone's favourite high street store, Zara. This striped, ruched-bodice frock - which, by the way, cost less than £40 - might be up there with our all-time favourite Kate looks.

However, in news that will surprise no-one, the off-the-shoulder dress from Zara is now out of stock. The Kate-effect meant that it took just a few hours for the dress to sell-out on the website, although you may get lucky in local stores.

We can certainly cross our fingers that it will be back online soon, but until then we’ve found similar styles that the Duchess would (probably) approve of.

Kate chose to wear her summer dress with wedge espadrilles and a white handbag, but these casual styles would look just as chic with white trainers and a simple summer hat.

Kate Middleton = our very own fashion queen.
