Florence Pugh made a dramatic entrance in Valentino Haute Couture at the “Don’t Worry Darling” red carpet premiere during the Venice Film Festival on Monday, Sept. 5. The Oscar-nominated star, who plays Alice Chambers in the much-anticipated film, chose a look from the Parisian fashion house’s fall/winter ’22/’23 collection, titled “The Beginning.”

Pugh showed off every angle of her sheer, corseted tulle dress, completed with poufy elbow-length sleeves, a floor-sweeping train, a front slit, and silver sequins that played up the shine of her Tiffany & Co. diamonds. She bared a hint of shapewear as she strutted across the carpet, including high-waisted hot pants and a strapless bralette. Pugh capped off the ensemble with what was perhaps the most eye-catching accessory of all: pointed-toe patent pumps with bow-adorned ankle straps and wispy black feathers that climbed to midshin. The leggy moment, styled by Rebecca Corbin-Murray, made waves as the actor posed with her grandmother for the cameras.

The star-studded cast also brought out some stunning Gucci looks, including brand muse Harry Styles‘s oversize pointed collar, expertly pressed atop a blue double-breasted blazer. Director Olivia Wilde also chose Gucci for the premiere, wearing a plunging yellow gown dripping with crystal chains. Creative Director Alessandro Michele, who also outfitted Jeremy O. Harris for the event, attended the premiere as well, bringing his impact full circle.

Meanwhile, Gemma Chan wore a gold metallic Louis Vuitton column dress with an architectural halter neckline and floral appliqué at the hem. Emerging actress Sydney Chandler showed off a sultry silhouette from Saint Laurent, and Chris Pine finished his brown Ralph Lauren suit with Ray-Ban Wayfarer sunglasses.
