It may officially be the first day of autumn, but the Duchess of Cambridge chose a decidedly summery ensemble while visiting London’s Battersea Park .

With the capital basking in unseasonably warm temperatures and bright sunshine, Kate donned a casual white T-shirt with a pair of pink pleated trousers, and simple white trainers for the occasion.

The mum of three spent time in the Old English Garden, meeting parents to hear how peer support groups have been coping during the coronavirus pandemic.

She also met with representatives from organisations including Home-Start, National Childbirth Trust and Mush to find out how they’ve relied on outdoor spaces like Battersea Park to enable mums, dads and children to enjoy socially-distanced meet-ups during lockdown.

If Kate’s effortlessly stylish outfit looks familiar, that’s because the trousers are part of a suit she wore back in March.

Priced at just £30, the Marks & Spencer trousers sold out after they got Kate's stamp of approval, while the shoes are the Superga Cotu Classic White, priced at £55.

After a summer where floral shirtdresses dominated Kate’s wardrobe, it’s great to see her switching it up with this chic but laid-back look. We also love the way she accessorised her top and trousers combo with delicate gold jewellery.

As well as popping on her much-loved Daniella Draper hoop earrings and Halcyon Days bangle, Kate sported two new necklaces today. The first was the Double Strand Beaded Satellite Chain Necklace, £85 from Spells of Love, which she layered over a triple disc chain.

Looking closely, you can just about make out a letter ‘C’ on one of the discs, which makes us think this is a personalised necklace dedicated to her three children, George, Charlotte and Louis.

The exact piece has yet to be identified, but if you’re after a similar version, the Personalised Triple Disc Necklace, £36, from Bloom Boutique, is available in silver and rose gold.
