The Duchess of Cambridge is a pro at elevating simple outfits, and her latest look channeled one of the the most classic styles of all: the French girl.

Kate Middleton has proven she can take any outfit and turn it into a knock out look, even if it's just a simple pair of skinny jeans and a wax jacket. And while we love to see her dolled up to the nines in a dazzling ballgown or stunning cocktail dress, we love her laid back looks too.

The British royal has a solid wardrobe of classic basics that she routinely jazzes up with statement pieces or a well-chosen designer accessory, and we love seeing how she works even the most simple look.

For her latest engagement, Kate paired a simple pair of blue jeans with an elegant designer blazer, mixing it with high street brand pieces as well as designer basics.

The Duchess was visiting the Natural History Museum, where she learned more about the Urban Nature Project, and got stuck into the arts and crafts activities with a group of children. Kate is a patron of the museum, so was very engaged in their plans to create more spaces for outdoor mindfulness.

She also revealed she keeps her own bees in Amner Hall, the residence she shares with her husband Prince William and three children, George, Charlotte and Louis, and brought some honey harvested from their hives for the school children to try.

For the event, Kate wore the Wool Cargo Pocket Blazer by French designer label Chloé, an elegant take on a utility-inspired blazer in grain de Poudre wool. The rich shade – called "wooden orange" – complemented her skin tone and added a warmth to her look. It features a gathered waist, peaked lapels and ribbed cuffs in a contrasting shade.

She wore this over a simple white Lauren Ralph Lauren Cotton-Blend Puff Sleeve Top, which features short cropped sleeves and a flattering scoop neckline. She paired this with classic straight leg jeans, the 'Favorite Cut' style from high street brand & Other Stories.

Keeping the classic cool girl vibes going, Kate added her Veja +NET SUSTAIN Esplar Sneakers in a subtle off-white shade with a metallic embellishment. She added a few gold chains, including the Spells of Love Double Strand Beaded Chain Necklace and Daniella Draper Trio Diamond Midnight Moon Necklace, engraved with her children's initials.

She wore her hair down in a full and loose blow dry, while her makeup was kept natural, with a peachy nude lip and soft brown eyeshadow.
