Kate Middleton’s Casual Outfits

We love it when the Duchess of Cambridge (Kate Middleton) wears casual clothing during her informal public engagements. Her laid back style is far more accessible to us mere mortals! Boots and jeans that are perfect for running errands, floaty dresses ideal for meeting friends for a coffee and jackets that are perfect for doing the school run on a drizzly day.

Although Kate’s known for her stunning gowns and chic skirt suits, it’s really fun to see her dressed down in casual outfits too. We particularly enjoy seeing her in jeans, a sweater and tennis shoes.

Which casual brands does Kate Middleton wear?

Kate’s well known for wearing couture designer gowns and elegant businesswear. But it’s her casual outfits that her fans love! When it comes to those less formal engagements, the Duchess will mix high end with high street. Here are some of the casual brands we’ve spotted her wearing over the last decade: H&M, Zara, ASOS, Massimo Dutti, GAP,, Barbour, Ralph Lauren, Superga, Veja.

We’re curating an archive of “casual Kate” looks on this page.   We’re adding more of her casual outfits all the time… but for now, browse a few of our favourites below. Perfect if you’re looking for a bit of style inspiration:
