There are few hair updates as simple, yet as impactful, as switching up your part. After several seasons dominated by center-parted lengths and deliberately undone styling, the side part is making a convincing return. The latest to make a case for its appeal? None other than Margot Robbie.

Attending Chanel’s Cruise 2026/2027 show in Australia, the actor and producer stepped out with a softly structured ‘buttercup bob,’ styled with a deep side part and flipped-out ends. The result was equal parts polished and quietly sophisticated. And while Robbie has recently been favoring the waterfall bob, this latest iteration feels notably sleeker, offering a more refined take on the trending cut.

“This bob is an effortless take on a classic jaw-length cut. It’s neat without feeling rigid, with soft ends and a clean shape that gives hair an expensive-looking finish,” Luke Hersheson, hairstylist and CEO of Hershesons previously told ELLE. In short, it trades lived-in texture for a more polished silhouette, with precise ends and subtle flicks upward that create a sharper finish.

Robbie’s latest style embodies the look perfectly, pairing a side part with softly sculpted ends for an take on the preppy bob. The part allows for a sweeping side bang, adding a touch of glamour to an otherwise classic cut.

When it comes to re-creating Robbie’s look, Talia Hurley, a stylist at Blue Tit London, recommends blow-drying the hair with a round brush for a glossy, classic finish. This will also help create added volume and the bend needed to achieve the look’s side-swept shape.

Luke Hersheson recommends finishing the look with a pea-sized amount of smoothing cream to add shine and tame flyaways without leaving the hair greasy, ensuring the style retains its polished, glossy finish.
