Kate Middleton's chocolate-brown trench coat, Chelsea boots and olive knit is my favourite autumn look she's worn in years

The Princess of Wales wore this look for her first visit to the Isle of Bute and it's chic, practical and easy to recreate

The Princess of Wales has styled some stunning autumn looks over the years but I can't remember one grabbing my attention instantly quite like what she just wore in Scotland. She and Prince William travelled to the Isle of Bute on 17th September and Kate ditched tailoring for a chocolate brown trench coat, roll-neck jumper, jeans and Chelsea boots.

Usually she either goes for full-on outdoorsy outfits or smart-casual. This combination is still polished and I can imagine so many of us wearing it for coffee dates with friends and autumn walks. It's easily one of my favourite seasonal looks I've seen her wear and Kate's brown trench is the first piece of this timeless outfit puzzle.

The checked lining gave it away as a Burberry trench coat at once and we saw it as she waved to people after arriving at Bute Shinty Club in Rothesay. This British clothing brand makes incredibly luxurious trenches, though there are so many other great options available at a more affordable price too and brown is back in a big way.

It was hugely popular last year and it's an autumn/winter fashion colour trend again. This is great news if you love neutrals and a dark brown trench is a softer alternative to black and still works beautifully with darker colours. It also doesn't tend to show stains or marks as much as tan.

The Princess of Wales wore her coat open to give a glimpse of her clothing underneath which consisted of a green roll-neck jumper and brown Jodhpur jeans from Holland Cooper. The knit was ribbed and fitted, creating a streamlined silhouette and making it so easy to tuck into her trousers.

The finishing touch was her boots and it's rare to see Kate in flats. She opted for suede Chelsea boots and since the Waleses are on the Isle of Bute to celebrate connection, community and volunteering, their outfits had to tick boxes for functionality.

She wore the boots to play some shinty and whilst she and Prince William helped with beach clean-up activities at Ettrick Bay. They were clearly very comfortable to wear and the cleated sole likely helped with grip in the drizzly weather too.

Later on in the day the future Queen also put on a baker boy hat for some extra coverage and the moss-green hue tied in with her jumper. Sticking to a colour palette of brown and earthy green for her entire outfit gave it a sense of minimalist sophistication.

These shades are also very seasonal and the longline trench with the streamlined jeans and fitted jumper all created a frame-elongating effect. If you aren't a fan of skinny jeans like the Princess of Wales, just go for whatever your favourite denim or trousers style is and drape them over the top of your Chelsea boots.

The combination will still look stunning and there's scope to add extra warmth with gloves and a scarf. Kate's hat would've helped her and she also buttoned up her coat when she and William were on the beach facing the sea breeze.

This is the couple's first official trip to the island and to the coastal town of Rothesay, which has a sweet link to them, as they're known as the Duke and Duchess of Rothesay when in Scotland.
