Due to the fluctuating temperature, spring dressing always calls for careful balance. Trying to navigate in-between seasons, frequently means we revert back to the hero pieces in our capsule wardrobe. And while there are countless styling formulas to try, there's a reason fashionable woman everywhere continues to rely on blazers and denim as their go-to.

Timeless and modern, a blazer instantly elevates any pair of jeans while maintaining the comfort we expect from our favourite denim. Indeed, the formula is so classic and easy to recreate that it was seen in many iterations on Spring/Summer 2026 runway shows.

At Valentino, girly long-line blazers were paired with flares, meanwhile, at Givenchy, the look was elevated through texture and styling, paring a leather blazer with dark-wash denim and layered jumbo jewel necklaces. At Celine impeccable tailoring styled with disc belts and crisp shirting upgraded an unassuming pair of peg leg jeans.

Elsewhere, stylish women everywhere have been styling their own versions of the blazer and jeans formula, with its most notable contender being Margot Robbie. The actress was seen in New York styling a boxy checkered blazer with a light-wash pair of straight-leg jeans.

What are the best jeans to pair with a blazer?

Regardless of the occasion, there are many ways to incorporate this hardworking duo into your wardrobe. Whether you're an avid baggy jean wearer or simply prefer a more narrow straight-leg silhouette, as seen above, the key lies in harmonising the look by incorporating contrasting proportions.

For a workwear-friendly look, take a cue from Margot Robbie and style a boxy blazer alongside a slimmer denim silhouette. To give the look some extra polish, reach for a slightly darker wash. Alternatively, for a new-season interpretation, mix a cropped blazer with a loose pair of wide-leg jeans, and you're all set.
