The Duchess of Cambridge headed out on a visit to London's Natural History Museum today in her favourite jeans, teamed with a blush-pink blazer from Chloé and casual Veja trainers.

Her long hair was styled in classic loose waves.

This is a look all of us can get on board with - it's simple but chic and perfect for summer.

And while the jacket may be a little pricy at £1,795, those who want to emulate the duchess's look can snap up the exact jeans - they're the Favourite Cut Jeans from stylish high street brand & Other Stories.

The Favourite Cut Jeans are made from organic cotton, and are fitted with added stretch for optimum comfort.

This design in particular is high waisted, with a slim leg style, full length, and features five pockets, as well as a zip and button fly front.

Plus they have belly loops around the waist, just in case you want to cinch in your waist a little more with a belt, or add the accessory for fun.

The Favourite Cut Jeans come in three washes, light blue, which the duchess opted for, as well as mid blue and black.

They are available in European dress sizes 24 to 32, and retail for £65, although sizes are selling out fast.

For those who can't get their hands on their size, fear not, as they also come in a stylish cropped cut.

The only difference is - yes, you guessed it - the cropped design have a cropped leg, which is slightly shorter and reaches just above the ankle.

The Favourite Cut Cropped are also made from stretchy organic cotton, are high waisted, have a straight leg, and are also £65.

But they come in more colourways, including ecru, acid blue, acid grey, washed grey, dusky blue, as well as mid blue and black.
