CNN  — 

Awards season is officially in full swing. After last week’s Golden Globes and Sunday’s Critics Choice Awards, the 75th Primetime Emmy Awards got underway at LA’s Peacock Theater on Monday — the third major red-carpet event in just eight days.

Many of the same stars were in attendance, and several trends that emerged at recent ceremonies continued, with black and red outfits dominating once again.

Actor and producer Katherine Heigl was there for a “Grey’s Anatomy” reunion and kept things classic with a scarlet Reem Acra dress and Marilyn Monroe-esque bob. “Succession” star Sarah Snook also channeled old Hollywood glamour in an elegant poppy-colored Vivienne Westwood gown, while British actor and musician Suki Waterhouse showed off her baby bump in a bright red Valentino Haute Couture gown with strategically placed side cut-outs.

Those opting for elegant black outfits included Lizzy Caplan (in vintage Yohji Yamamoto), Christina Ricci (in plunging Saint Laurent) and Riley Keough (in Chanel). “The Bear” star Ayo Edebiri was, meanwhile, among the evening’s best-dressed in a black Louis Vuitton leather bustier gown with a structured balloon skirt.

It may only be January, but spring was definitely in the air on the Emmys red carpet. Plenty of attendees opted for fresh greens — from Jessica Chastain’s eye-catching chartreuse Gucci dress to “Ted Lasso” star Hannah Waddingham’s soft mint beaded Marchesa gown.

Floral detailing was on show as well: On actor and comedian Ali Wong’s embroidered satin Louis Vuitton skirt, Simona Tabasco’s flower decoupage dress by Marni and her “The White Lotus” co-star Meghann Fahy’s custom Armani Privé dress, one of many to feature rose motifs.

The theme carried over to menswear, too. Donald Glover, nominated as a writer for “Swarm,” wore a velvet top and pants with flower detailing by Bode. Awards host Anthony Anderson also put a fun spin on black-tie tradition in an Etro tuxedo with beaded lily design.
