Kate just stepped out in a £90 jumper from this cult French knitwear brand

Kate gave families on the school run a sweet surprise this morning (Wednesday 29 January) when she arrived at Stockwell Gardens Nursery and Pre-School to help serve breakfast to the pupils.

The mum-of-three made an early start to joined staff and students at the London Early Years Foundation, where she learned about the importance of nutritious food in childhood development as part of her recently-announced Early Years initiative.

For the low-key appearance, Kate was dressed in a chic teal coat and black jeans, topped off with her signature bouncy blow-dry. However, all eyes were firmly on her stylish frill-necked jumper.

The cosy cream knit was quickly identified to be from cult French brand Sezane, where it costs £90 – if you can track it down, that is. Somewhat predictably, the Kate effect has already struck and it’s currently showing as sold out, in both Kate’s light colourway and the black version too.

The Duchess of Cambridge accessorised the chic piece with an even more affordable high street find – her beloved filigree Accessorize earrings, which she has worn on multiple occasions, and may have paid as little as £1.50 for, as they are a sale item that was reduced over the summer.

Kate got into the swing of things by chatting with children while they ate their meal, and was even pictured handing out high fives to the assembled group.

‘It’s great to visit places like this where communities come together to support one another,’ HELLO! magazine reports that Kate said during her visit.

‘Last week I launched a UK wide survey on early childhood because I want to hear society’s views about raising the next generation. I’m so happy that over 100,000 people from all across the UK have already completed it, and I can’t wait to see the results.’
