If any celebrity is a good temperature check for the season’s most important trends, it’s Sofia Richie Grainge. Owning a wardrobe rotation drenched in the quiet luxury aesthetic, the model keeps her daily looks clean and simple, only ever occasionally throwing in a new-season trend to add some extra dimension to a look. So, when she does integrate a new style into her wardrobe, you know it’s going to be an important one.

Stepping out for an evening event in L.A., Richie Grainge assembled a typically chic ensemble complete with one of the biggest jacket trends of the season. Finishing off her denim with an oversized leather bomber jacket, Richie Grainge’s outfit conveyed an easy energy that perfectly complimented her off-duty look.

Set to be one of the biggest jacket trends of the season, oversized leather bomber jackets dominated street-style crowds during fashion month in September. Favoured by showgoers and off-duty models alike, the trend permeated the city’s streets, rivalling the boxy blazers that typically dominate across fashion month.

While I noticed the jacket trend styled up in several ways, it was a blue jeans and oversized jacket pairing that I saw time and again in September. Simultaneously cool-girl-coded and incredibly comfortable, the outsize bomber (whether leather, suede or fabric) offers a wearable and cosy look you’ll want to keep coming back to.

A firm staple in the wardrobe rotations of fashion people in London and Paris, it’s evident that the trend is set to ripple out from here. Whilst they might not be as warm as your favourite puffa or wool coat, I find that this jacket trend is far cosier than I ever expected. Padded with extra cushioning to achieve the bomber silhouette, the leather exterior retains body heat, whilst the oversized cut means that you can layer jumpers and thermals undeath without adding too much bulk.

Catering to the growing demand, brands have been quick to offer their take on the trend. Saint Laurent’s styles’ have been snapped up by Bella Hadid and Hailey Bieber, but brands such as Reformation and Massimo Dutti all stock chic versions, too.
