The look could be seen in “Blindspot” actress Jaimie Alexander’s green gown by Genny, Heidi Klum’s flapper-fringe number by Marchesa, “Chicago P.D.” star Sophia Bush’s otherwise-understated little black bridesmaids dresses sydney by Narciso Rodriguez and the blue strapless gown from the pre-fall 2016 Reem Acra collection worn by “Downton Abbey’s” Joanne Froggatt.

Katy Perry, a stunner in a rose pink Prada gown with a plunging — but comparatively safe — neckline, managed to draw even more attention to the trend by pointing to her bosom and remarking to red-carpet commentator Ryan Seacrest that she “brought the globes.”

Olivia Wilde wore a custom Michael Kors Collection wine-colored silk crepe halter gown with sequin embellishments that made her a two-fer in the trend department: The night’s other big theme was a surfeit of sequins, which came down the carpet with the festive feel of a freshly uncorked Jeroboam of bubbly.

Among the standouts of the evening’s sparkle posse were nominee Regina King (“American Crime”) in a sleeveless gold metallic floral sequin dress by Krikor Jabotian accessorized with a regal-looking cape, nominee Uzo Aduba (“Orange Is the New Black”) in a sparkly gown from the Talbot Runhof Resort 2016 collection and Julianne Moore in a midnight-blue, sequin-covered, draped-back dress by her awards-show date Tom Ford. Brie Larson’s custom gold gown from the Calvin Klein collection was embellished with so much metal, she likened the dress to “wearing Joan of Arc armor.”

Kate Hudson wore a custom beaded crepe bandeau-top gown from the Michael Kors collection, but it was another Kate — last name Bosworth — who set the sequin bar even before she’d left the limousine. Bosworth posted photos of her pink sequin Dolce & Gabbana gown to social media in advance of her arrival, and the confection looked like a wearable glass of pink Champagne.

Bosworth’s strapless gown also keyed into one of the smaller trends of the night: the bare and off-the-shoulder looks sported by the likes of Kate Winslet in a Ralph Lauren Collection royal blue silk crepe crisscross halter budget wedding dresses, Lady Gaga in a custom black Atelier Versace gown with exaggerated hips and a sweetheart neckline, Gina Rodriguez in a blue Zac Posen gown and Amy Schumer in a black and white color-blocked Prabal Gurung gown that was also notable for the fact that it had something that’s often in short supply on the red carpet: pockets.
