You have almost certainly scrolled past it already this week – a gauzy, lace-trimmed dress that looks like it was lifted straight from your grandmother’s linen closet. Maybe you double-tapped it on Bella Hadid’s feed. Maybe you spotted it on a Chloé runway recap. Either way, something about it stopped you, because it looked simultaneously like pajamas and like the coolest thing anyone has ever worn outside the house. That tension is exactly the point. And the trend has a name you probably did not see coming.

How your grandmother’s closet became fashion’s favorite mood board

This year has delivered an almost comical number of so-called granny trends. Orthopaedic sandals, silk headscarves, curtain-worthy florals, almond-toe pumps – items you are now just as likely to spot on a twenty-something in Dalston as on an actual senior citizen. The entire aesthetic raises a fair question: what does a granny actually look like in 2026?

If you rewind to 2014, the fashion conversation was dominated by a very different cultural artifact. The viral slogan tee reading “This Is What a Feminist Looks Like” was photographed on Emma Watson, Alexa Chung, Lena Dunham, and even Ed Miliband. That particular brand of hashtag feminism eventually faded. Now the style pendulum has swung toward something far more tactile and, frankly, far more interesting – borrowing not from political messaging but from the intimate, domestic corners of an older woman’s wardrobe. The nightgown, specifically, has become one of summer 2026’s defining dress silhouettes.

What defines the look – and who is wearing it

The nightie dress as it exists on the runways at Chloé, Victoria Beckham, and other major houses is built on a few non-negotiable elements. Lightweight cotton or silk fabric comes first. Then a loose-fitting silhouette that skims rather than clings. Finally, whimsical details – ribbons, lace, broderie anglaise – that give the garment its dreamy, slightly anachronistic charm.

The roster of women already embracing the trend reads like a who’s-who of contemporary cool. Bella Hadid, Alexa Chung, Kaia Gerber, and Olivia Rodrigo have all been spotted in variations of the look. And the appeal makes sense once you see it in motion: the nightie dress is effortless without being sloppy, romantic without being costume-y. There is more than a hint of The Virgin Suicides in its DNA, that hazy, ethereal quality that hovers somewhere between innocence and knowing sophistication.

Vogue contributing editor Julia Hobbs has spoken about how she styles her own go-to version – a ruffled, broderie anglaise cotton minidress from Petra Collins’s I’m Sorry label – pairing it with bug-eye sunglasses and silver jewelry when she is in LA. She has described the overall mood as something like grown-up girlhood, a phrase that neatly captures the balance between youthful ease and intentional polish.

How to actually pull it off without looking like you forgot to get dressed

The key to wearing a nightgown as daywear is grounding it with structured accessories. Fashion journalist Harling Ross, who launched a capsule collection of nightie-inspired dresses with the label If Only If, has stressed that the right shoes and bag make all the difference. Loafers and chunky sandals provide the architectural weight that a floaty dress needs. A smattering of jewelry adds deliberate detail. And a bag with real presence – think suede or leather, something with substance – anchors the whole outfit firmly in real life rather than letting it drift into sleepwear territory.

When it comes to shopping, a few labels stand out for specific iterations of the trend. Dôen is your destination for broderie anglaise. Free People delivers a more modern bohemian take. If Only If specializes in loose, babydoll silhouettes. But if you want that unmistakable old-world romanticism – the kind that conjures images of an old lady standing on the deck of the Titanic clutching a legendary jewel – vintage is the way to go. Etsy and eBay are both rich hunting grounds, and searching for a vintage Edwardian nightie dress will surface some genuinely spectacular finds.

One practical note worth paying attention to: fabric matters enormously. Avoid anything synthetic. Classic cottons and silks perform far better in the heat, and they also eliminate the risk of static cling, which can turn a romantic silhouette into something decidedly less glamorous in a matter of seconds.

Your new summer uniform, hiding in plain sight

What makes this trend so compelling is how counterintuitive it feels. A nightgown should not work as a dress. And yet, styled with intention – structured footwear, considered accessories, natural fabrics – it becomes one of the most relaxed yet put-together looks of the season. You now know the specific brands, the search terms for vintage sourcing, and the styling rules that keep the whole thing from veering into costume. The only real question left is whether you will reach for cotton or silk first.
