Margot Robbie’s summer wardrobe is full of every It-girl’s favorite staples: classic tank tops and straight-leg jeans, along with breezy maxi dresses and, of course, the inescapable Alaïa mesh ballet flats. Now officially back at work, though, the actor’s on-duty style is more bombshell glamour than pared-back chic.

For a photocall for her new film A Big Bold Beautiful Journey in Los Angeles on Wednesday night, Robbie opted for one of her favorite red-carpet silhouettes: a corseted mini. This time around, the cinched-in dress, featuring exposed boning on the bodice and padded hips, came via Stella McCartney’s resort 2026 collection. To complete the look, Robbie swapped her trusty ballerinas for a pair of strappy black heels.

It makes sense that Robbie would turn to her go-to style for her first red-carpet appearance since giving birth to her son last autumn. The actor previously wore a custom red corseted minidress by London-based Turkish-born designer Dilara Findikoğlu during the Barbie press tour in 2023, before sporting a gold embellished corset from Thierry Mugler’s spring 1996 collection at the Vanity Fair Oscar Party in 2024.

While the silhouette has long been a favorite for Robbie, the minidress has been experiencing something of a revival this summer, with higher hemlines being the order of the day. From babydoll nighties to more fitted shifts, expect the trend to continue well into the autumn–paired with slouchy boots and a faux-fur coat slung over the top.
