Let’s talk about the effortless trainer and jean combo. It is the perfect antidote for those “I have nothing to wear" days — so save the mounting piles of clothes strewn over your bedroom floor, and hit this fashion fail-safe equation that always works.

This pairing has transcended trends, decades, and sub-genres of personal style to become a go-to uniform for quite literally, everyone. From celebrity strolls (we’re looking at you Hailey Bieber) to your effortlessly chic best friend on her daily commute.

But do you sometimes feel like this supposedly simple combo is just a little off? Chances are your denim-to-trainer ratio is to blame. The key? Getting the silhouette (and the vibe) right. Choose the jean shape that complements your trainer style, not conflicts with it. Think dark wash jeans that make bright colours look bolder, or wide legs to balance out the proportions of chunky sports styles.

Allow us to show you how. Here are 6 fail-safe trainer and jeans combos that are certifiably stylish and fresh, including some of the best new trends to incorporate into your autumn wardrobe now.

Colour pop and dark wash

Bright, colourful trainers breathe new life into classic indigo denim. The contrast is clean, fresh and looks intentional. The key is keeping the rest simple — think white vest or tee, a cardigan thrown about your shoulders and some tinted sunnies. Voila.

    Statement and cuffed hem

    Sculptural, sporty trainers (like this wearer's Cecilie Bahnsen x Asics pair) + loose-fit denim = chef’s kiss. The cuffed hem of the jeans showcases the details of the trainer, to make them a focal point of your outfit. When they look this good, why hide them?

    Indie sleaze is calling! Channel the look of the era with old school Adidas Tokyo trainers (we love this wearer's gold pair) and slim-leg jeans. Add a blazer or bomber jacket, a leopard print scarf, and you're back in 2010 — in all the right ways.

    Low rise and monochrome

    Yep, Noughties energy is alive and well. Low rise jeans are back (if you dare to wear) but not in the way you might think. Add a smart, structured jacket and crisp white tee for a more grown-up take on the denim trend. Monochromatic trainers to finish off the look ensure comfort while looking chic.

    Black and red

    Red trainers continue to be having a moment — the Puma Speedcats have been spotted on everyone from Emily Ratajkowski to Dua Lipa. Pairing them with black jeans ensures that the trainers do the real talking. Bonus points for matching red accessories and autumnal, cosy styling — faux-fur is going to be everywhere this season.

    Animal print and ultra-long

    Don’t be daunted by patterned trainers. It’s an easy way to add an extra something to a simple outfit. A flash of leopard print peaking out from underneath ultra-long, floor-length jeans will ease you into the trend nicely.
