Rose Byrne Wore Ralph Lauren Collection To The ‘If I Had Legs I’d Kick You’ London Film Festival Screening

There seems to be a quiet revolution happening on the red carpet — Bedsheet Couture is officially a thing.

From Tessa Thompson’s Erdem look the night before to Rose Byrne’s Ralph Lauren Collection Spring 2026 gown at the If I Had Legs I’d Kick You screening during the London Film Festival last night, it’s clear that rumpled refinement is having a moment.

With all due respect to the designer, this gown could easily be mistaken for a luxuriously wrapped linen sheet — albeit one styled by a Park Avenue princess, thanks to that delicate bow accent.

Rose allows the minimalist design to take centre stage, exuding that “just rolled out of bed” kind of energy. And yes, I mean that quite literally — the creases are unapologetically visible. It’s normally one of my biggest bugbears, but it humourously works here, given what the dress appears to be.

If Bedsheet Couture is the new wave, perhaps this is the evolution of comfort dressing. Jean Schlumberger by Tiffany & Co. earrings and a ring completed her quietly luxurious moment.

Stylist: Kate Young.
