‘Wuthering Heights’ Star Margot Robbie Just Confirmed Summer 2026’s Biggest Fashion Trend Is Basically Underwear
Celebrity street style has a funny way of turning something totally ordinary into a full-blown trend report, and this week, Margot Robbie did exactly that while running errands with her mom in Paris. What started as a casual outing has since become one of the most talked-about fashion moments of the summer.
The Oscar-nominated actress has spent much of the past year experimenting with increasingly daring red carpet choices, from sheer gowns to lace-trimmed slip dresses. But it was her latest off-duty look, spotted stepping out of the Ritz Hotel, that really got people talking.
Robbie was photographed wearing a butter yellow two-piece set from the label Dôen, pairing the brand’s lace-trimmed silk-charmeuse mini skirt with its matching lace-trimmed camisole top. The combination gave off an unmistakably sleepwear-inspired look, blurring the line between loungewear and an actual outfit meant for public view.
That silhouette has quickly become the story of the summer in fashion circles, with multiple outlets pointing to Robbie’s appearance as further proof that lingerie-inspired dressing has cemented itself as the season’s defining trend. She wasn’t dressing in isolation either, since several other major style figures have leaned into the same aesthetic in recent weeks.
Hailey Bieber recently stepped out in a vintage slip dress from John Galliano’s Fall 2005 collection for Christian Dior, while Bella Hadid showcased a similar look while promoting her fragrance brand. Millie Bobby Brown and Kylie Jenner have also been cited as recent adopters of the same nightwear-meets-daywear approach, suggesting this isn’t a one-off moment but a genuine shift in how celebrities are approaching casual dressing.
Robbie completed her Paris look with The Row’s Elastic Ballet Slipper in black, a shoe style that fits neatly into the broader hybrid Mary Jane trend currently dominating footwear conversations. She accessorized with Chanel’s Cat-Eye Sunglasses and carried the brand’s Spring/Summer 2026 Small Shopping Bag, finishing things off with a floppy black hat that seemed aimed at helping her go incognito while walking the city streets with her mother, Sarie Kessler.
Not everyone has embraced the look with open arms, though. Some social media users questioned the outfit directly, with one person asking why Robbie appeared to be “shopping in her nightie,” while another wondered aloud whether she was simply “out in her underwear.”
That kind of divided reaction has become something of a pattern for lingerie-inspired dressing in general, a trend that thrives on blurring boundaries precisely because it makes some viewers uncomfortable. Fashion outlets have largely framed the criticism as part of the broader conversation the trend is designed to spark, rather than a sign it’s losing momentum.
This latest look also arrives amid a broader stretch of headline-making fashion choices for Robbie, who has spent much of the year experimenting with sheer fabrics, naked dressing, and boudoir-inspired silhouettes across both red carpet appearances and casual outings. Her Paris ensemble simply took that same energy and applied it to something as mundane as an afternoon outing with family.

Whether or not the lingerie-as-outerwear trend sticks around beyond the summer remains to be seen, but for now, Robbie’s Dôen set has firmly planted her at the center of one of 2026’s most talked-about style conversations.
