Boudoir dressing has broken out of the bedroom and onto the red carpet. The slip dress trend that once lived quietly in off-duty street style, all lace trim and delicate straps worn with trainers, has now taken over Hollywood's biggest nights. Stars are trading structured ballgowns for sheer lace and cotton nightdresses that look plucked straight from the underwear-as-outerwear playbook.

And this isn't just a run of coincidentally similar outfits. It's a pushback against the rigid, boned corsetry and hyper-tailored glamour that has ruled red-carpet dressing for decades, swapped for something softer, undone, and a lot more intimate. Here's who is leading the charge.

Nicole Kidman, Atelier Versace

At the Practical Magic 2 LA premiere, Kidman turned up in a semi-sheer black lace Atelier Versace gown, the debut look from Pieter Mulier at the house, built around hand intarsia lace and a lingerie-inspired silhouette. That Mulier picked sleepwear as his opening statement at a house built on power dressing says a lot. It's basically given the whole trend a high-fashion stamp of approval overnight.

Joey King, Custom Miu Miu

King went softer on the same press tour in a custom butter-yellow Miu Miu slip worn over matching lingerie, with puff sleeves and gentle ruffles. Next to Kidman's gothic siren energy, King's pastel romanticism showed just how wide this trend can stretch, from menacing to sweetly innocent, on one red carpet.

Olivia Rodrigo, Victoria's Secret Lace Slip

Rodrigo took the trend into pure nostalgia in a vintage 1990s Victoria's Secret white lace slip micro minidress, featuring a plunging V-neckline trimmed with floral lace, delicate straps and a ruffled scalloped hemline. The archival nightdress taps straight into the nineties grunge glam once defined by Kate Moss, and paired with an archival handbag, it shows just how easily an authentic boudoir piece translates into high-street style.

Zoë Kravitz, Off-Duty Mini Slip

Kravitz offered a masterclass in off-duty boudoir dressing in a black silk mini slip dress accented with a delicate black lace bustline. Pairing the whisper-weight nightdress with red leather ballet flats, dark oval sunglasses and a woven straw tote, she strips away the red-carpet drama entirely, proving the silhouette can look effortlessly cool and wearable for everyday summer dressing rather than reserved for the step and repeat.

Dakota Fanning, Victorian Rodarte

Fanning showcases Rodarte's pastel bias-cut silk charmeuse nightgown dresses with olive and butter-yellow accents, sheer lace inlays, and subtle leg slits that reference both 1920s flapper styles and Victorian sleepwear. Designed by Kate and Laura Mulleavy, known for their ethereal gothic-romantic sensibility, these looks highlight softness and heirloom textures, showcasing romantic nostalgia with vintage craftsmanship.

How To Wear the Sleepwear Core Trend off the Red Carpet

For everyday dressing, the translation is simple. Pick a slip in solid silk or cotton lace, layer it rather than wearing it alone, then ground it with boots or a bit of tailoring. Whether this becomes genuine high-street fashion or stays a celebrity-only spectacle depends on how far designers push it beyond the red carpet and into ready-to-wear. Right now, all signs point to staying power.
