There’s a particular kind of chaos that happens when you show up somewhere in what looks suspiciously like your bedtime outfit, and instead of getting side-eyed, you get complimented. Welcome to sleepwear fashion in 2026, where the line between ‘I just rolled out of bed’ and ‘I’m dressed for a party’ has basically dissolved.

Pyjamas, real ones, silky, striped, sometimes monogrammed, have quietly become one of the most confident things a person can wear out. Not loungewear pretending to be daywear. Actual pyjamas, styled like they mean it.

Blame the pandemic hangover if you want, but trend forecasters have been tracking this for a while. Berlin-based analyst Carl Tillessen has a theory that’s stuck with a lot of editors this year: the pyjama look erases the old boundaries between work and leisure, indoors and out. It’s a fantasy of a life with no dress code, no 9-to-5, no representative duties, just soft fabric and freedom. He even borrows a line from Karl Lagerfeld, who once suggested a crisp, piped silk-satin pyjama was the socially acceptable way to signal you hadn’t completely given up, unlike your neighbour slumming it in a baggy tracksuit.

Runways caught on fast. Dolce & Gabbana sent pyjama-inspired tailoring down the spring/summer runway, all fluid trousers and matching tops that could pass for eveningwear if you squint. Jacquemus went a step further, teaming up with Scandinavian homeware brand Tekla for a collection that blurred bedroom and boulevard so completely nobody quite knew where to draw the line anymore.

Celebrities, naturally, got there first. Rihanna made headlines years ago for stepping onto a red carpet in Pucci sleepwear, and she’s arguably the reason ‘boudoir dressing’ became a phrase people actually use in styling meetings. Billie Eilish took it somewhere weirder and better, showing up to the LACMA Art + Film Gala in matching Gucci pyjamas, slippers, and an honest-to-goodness comforter, a look so committed it looped back around to genius. More recently, the aesthetic has crept into red-carpet season more broadly, with stars treating silk sets the way they’d treat a slip dress: as eveningwear, full stop.

The trick to pulling it off, according to most stylists, is refusing to make it cosy. Pair the set with heels, not slippers. Add real jewellery. Do your hair. The moment you throw on a cardigan and skip makeup, you’ve tipped from ‘fashion statement’ into ‘did I forget where I was going.’ Fabric matters too, this is a silk-and-satin trend, not a flannel one, which is partly why it photographs so well under party lighting.

There’s also a quieter shift happening alongside it: what stylists are calling ‘athlegance,’ a more polished cousin of athleisure, built from finer materials and better cuts, designed for entrances rather than Netflix marathons. Pyjama dressing fits neatly into that same mood, comfort with intention, not comfort as an excuse.

Whether this is peak laziness dressed up as luxury or genuinely the smartest evolution in eveningwear in years depends on who you ask. Either way, don’t be shocked if your next dinner invite comes with an unspoken dress code: bring your best pyjamas.
