Kate Middleton's Warehouse jumper.

The Wave Pointelle Jumper is €51/£39 and the Duchess of Cambridge was spotted wearing the gorgeous berry-coloured shade today. We have a feeling this piece, featuring a fab scalloped neckline and an affordable price, will sell out in record time. If you're not feeling the purple shade, you can choose from tan, black, khaki and white and we love the fact that a piece like this can be matched with so much. Attending an event at London's Natural History Museum, the mum of three wore what can only be described as the perfect autumn winter ensemble. The Duchess has been spotted in some fashion-forward looks of late and has been favouring trousers over printed skirts and dresses, previously her trademark look. Pairing the cosy knit with khaki green culottes, Kate Middleton topped the look off with a Chanel bag and honestly, what a divine ensemble. The trousers are from Jigsaw, a brand the Duchess used to work for back in the day (as an accessories buyer FYI) and we couldn't be more obsessed. The Gathered Waist Culottes are on sale at the moment having been reduced from £130 to £89. Kate has been a patron of the Natural History Museum since 2013 and today, she visited the Angela Marmont centre for UK biodiversity located at the museum.

Staff at the facility are developing new and efficient methods to protect and conserve wildlife and today, the Duchess got to see their work first-hand. Today's outing comes ahead of next week's royal tour to Pakistan with Kate Middleton and Prince William travelling to the country for four days in total. https://twitter.com/KensingtonRoyal/status/1181888901352448001
