If you thought trouser suits were exclusively for the office, it's time to re-evaluate. In fact, what started out as a humble women's workwear essential has quickly turned into a capsule wardrobe staple, with the best trouser suits being appropriate for just about any occasion with the right styling tips.

Looking back at the most stylish women of the past few decades, it's clear that there was a running theme among their wardrobes – they all embraced the trouser suit trend. Be it Bianca Jagger in the '70s with her iconic ivory wedding suit and three-piece party tailoring, or Gwyneth Paltrow rocking Gucci's signature red velvet suit in 1996, the fashion set has never shied away from structured tailoring when it comes to red carpet looks and after-dark dressing.

So, it's hardly surprising that in 2024 our favourite brands, from H&M and Reiss to Aligne and M&S, are looking to the past for design inspiration. This year it's all about the tuxedo jacket, which first came to the fore back in 1966 when Yves Saint Laurent introduced the iconic Le Smoking. We love ME+EM's reference to the luxury house this season, with its feminine take on the traditionally masculine black tie classic.

The best trouser suits don't need to be saved for special occasions, though. You can keep things office-appropriate by layering structured blazers over crisp white shirts and opting for on-trend slingback kitten heels or chunky trainers.

Starting to think about your spring/summer wardrobe? Simply swap out weighty wool trouser suits for this season's must-have linen sets – they'll work with T-shirts day-to-day and also make excellent resortwear when paired with a timeless black swimsuit.
