Sienna Miller wore a black velvet gown that nearly plummeted to her belly button at the 81st Venice International Film Festival on Friday, Sept. 6. The dress was vintage Giorgio Armani but the design felt right at home on a red carpet peppered with plunging necklines. Even Lady Gaga chose a plunging Christian Dior Haute Couture gown to walk the Joker: Folie à Deux red carpet with fiancé Michael Polansky. Julianne Moore also got the memo in time to commission a gold sequin gown with long sleeves and—yes—a deep V-neck from Bottega Veneta.
But the trend didn't stop there. Across the globe, Dakota Johnson was busy delivering her bohemian spin on the deep V-neck at the Bulgari Studio Party during New York Fashion Week, pairing a chocolate brown lace slip dress with an oversized pendant. Then, the very same night in Los Angeles, Meghann Fahy and Nicole Kidman both turned up in clavicle-baring gowns for the premiere of their new Netflix series The Perfect Couple. Styled by Jason Bolden, Kidman opted for a shimmering, semi-sheer Ferragamo halter dress. Fahy and stylist Thomas Carter Phillips, on the other hand, selected a black lace dress from Victoria Beckham.
