Pippa Middleton’s check blazer, neutral roll neck knit and blue jeans are the anti-trend essentials you need in your autumn wardrobe

Pippa Middleton always looks incredibly elegant in her summer dresses when sitting in the stands watching the tennis at Wimbledon, but if you ask me, autumn is where she really comes into her own, style-wise.

Case in point: this very chic ensemble. A blazer and jeans are key autumn capsule wardrobe staples, and really do make up the basics of my everyday wardrobe. This failsafe combination will help you navigate even the trickiest transitional weather days. Unseasonably warm? Take off the blazer and drape it over your shoulders! And if it's raining you can add ankle boots rather than ballet pumps or your best white trainers.

It works in all colour combinations, whether that's Pippa's white jeans and a blue blazer, or a super smart black blazer teamed with leopard print jeans.

Kate Middleton's sister was pictured out and about in London back in 2012, but this outfit looks every bit as good today. She teamed a pair of dark wash blue skinny jeans with an oatmeal-coloured roll neck jumper, adding this effortlessly elegant plaid jacket.

It's a very kind of Balmoral-ready, countryside chic look that we can totally imagine the Princess of Wales wearing, and is easy to recreate from the current high street collections.

Pippa added a roomy black bag and a gold pinkie ring to her look, but to take this look to another level you could try the bestselling pair of By Pariah earrings that her sister loves, and have just landed back in stock. Run, don't walk...
