Embrace your inner English eccentric because Isabel Marant, Stella McCartney and Balenciaga all revived heritage checks this season. To avoid looking like an aging member of the royal family, style yours with denim - this works for outerwear as much as it does tweed blouses. Wear wide-leg plaid trousers or a tweed mini skirt with a simple white T-shirt. Double-breasted coat, £475, Ganni

Whether you go wide-leg or slim-cut, the suit is big news this season. This isn't an homage to the 80s though - keep yours nipped in at the waist for a more flattering silhouette. Navy trousers, £125, jacket, £230, Reiss

The trench coat never really went out of fashion, but it's received a modern twist this season under the eyes of Balenciaga who served up oversized styles with asymmetric wind flaps. If your budget won't quite stretch to that, then look for midi-length versions that, to the untrained fashion eye, look a little big. Wear it open and, if you do decide to use the belt, never wrap it tightly. Gaberdine trench coat, £1,915, Balenciaga

Shades of red prevailed on the autumn/winter 17 catwalks, so treat yourself to Zara's crimson jacquard midi dress - a great day-to-night option - and team with a pair of ankle boots. Jacquard dress, £59.99, Zara

If you still haven't invested in a pair of kitten heels, now's the time to do so. Comfortable and chic, pair yours with denim, midi-skirts or culottes. Slingback velvet pumps, £420, Prada

If you're going to invest in a bag this season, make sure it's round. Mulberry, Chloe, Roksanda Ilincic and Jerome Dreyfuss all opted for this graphic, bold style this season. Leather round bag, £250, Mulberry

The antidote to bodycon and skinny jeans, this season's new silhouette is voluminous. The wide-leg trouser is key here, and, contrary to popular belief, you don't need to be tall and willowy to wear it. Just make sure that whatever top you're wearing is fitted and steer clear of chunky fabrics. High-waisted styles are the most flattering. Satin-trimmed wool trousers, £1,075, Alexander McQueen

The majority of us want boots that can be worn from day to night. While we might have marvelled at Yves Saint Laurent's bewjewelled knee-highs, it's Isabel Marant's slouchy ankle boots that have won us over in earnest. They reference the 80s without being too obvious, while the chunky heel will ensure that sore feet is never a problem. The over-the-knee version is also a strong option for those feeling bold. Leather ankle boots, £690, Isabel Marant

The statement shirt made the big-time last season and its reign will continue though autumn/winter 2017. As ideal for the office as it is for evening drinks, no wardrobe is complete without one. Consider puff sleeves, belted waists, extra long sleeves and detailed cuffs. Cocoon sleeve shirt, £65, Kitri

The beret is back, courtesy of Dior, who offered leather styles, and Gucci, whose red felt versions played up to its eclectic signature. Rihanna, Winnie Harlow, Clemence Poesy and Adwoa Aboah have all been seen in them over the past few months. Pull yours firmly over your head rather than at a jaunty angle - no one wants to look like a French parody. Wool beret, £160, Gucci
