It can be a struggle transitioning the bright looks of summer to richer, deeper tones for autumn, but leave it to Kate Middleton to show us how. 

The Duchess of Cambridge stunned in a rich and glamorous outfit this morning as she visited the National History Museum, turning heads with her daring combination of olive and wine tones.

Kate paired wide-legged olive green culottes by Jigsaw, the esteemed British label that Kate actually worked for before marrying Prince William, with a rich wine knit top by Warehouse, with intricate pointelle detailing on the neck and sleeves and with a high scalloped neckline.

The colour palette and silhouette brought to mind 1930s fashion, an on-trend mix of masculine and feminine detailing that looked effortlessly chic. 

Adding to this were the Duchess's sophisticated accessories: her trusty Tod's Fringed Leather Pumps in a stunning burgundy shade, matched with a small quilted handbag by Chanel in the same shade and featured a gold handle. 

Autumn was clearly on her mind, as she finished her look with a pair of Asprey Woodland Collection Oak Leaf hoop earrings. 

Even better, you can recreate the look yourself, as the trousers are still available and cost £89 (roughly €100) reduced from £130, while the jumper costs €51. 

The Duchess has been the patron of the Natural History Museum since 2013, following in the footsteps of Prince William's mother Princess Diana, who held the patronage for four years until 1993.
