has been pictured looking typically stylish this week while in . On Sunday, she chose a simple one-shoulder black dress from a British high street label, pairing it with a denim jacket and an Aspinal of London handbag - we think this might just be the perfect summer outfit.

If you like the idea of a black dress, we've done the research and Zara's frock with an asymmetric neckline and swishy tiered skirt is from Me+Em. In a cheesecloth fabric made from lightweight cotton, it's an ideal breezy dress for a warm-weather outing. originally cost £150 but was reduced in the sale and flew off the shelves. At the time of writing, it's only available in one size.

If you want to get your hands on a similar style, the Daily Express has found an almost identical design from Nobody's Child, along with other high-street alternatives from brands loved by Zara.

This one-shoulder option from Nobody's Child perfectly replicates Zara's look. Made from 100% cotton with a shirred bodice and A-line skirt, we'd take style notes from Zara and pair this with a denim jacket. If you like the asymmetric neckline but would prefer some colour, there are powder blue and leopard-print options, too.

Nobody's Child is a royal favourite; Princess Kate has been spotted wearing the British brand on several occasions, along with other senior royals, including Queen Camilla and Duchess Sophie.

If you would prefer an off-the-shoulder design then check out this linen bardot dress from Dorothy Perkins. We love the ruffle detail and A-line cut. This versatile look would look great if you paired it with wedges, for an extra bit of height.

You can get an extra 20% off using the code EXTRA20 at the checkout.

Here's another black cotton dress, this time with deep v-neckline and ruffled cropped sleeves. Like Zara's dress, it has pockets, which give it a relaxed feel. If you are looking for a splash of colour then try the green-and-white floral alternative. Both come in petite and regular lengths and are available in sizes 4-22.

Boden is another affordable label loved by the Royal Family and Zara has been spotted in its collection several times, as has Princess Kate, who is a fan of their blouses and dresses.

If you would prefer a dress that covers your shoulders, then try this affordable design from Next. It is made from a soft cotton jersey material, and we love the ruched sleeve detail and flowing skirt. It also comes in red. We think this would look great with white trainers, a look that Zara is fond of. Earlier this week she rocked with a pair of crisp Superga plimsolls.

This floaty smock dress from New Look is another bargain. This lightweight cotton dress with a v-neckline and three-quarter-length sleeves with a broderie detail is a pretty summer-holiday option that you can throw in your suitcase. It also comes in khaki, blue and red.
