The 2020 SAG Awards were a stylish affair!

The A-listers stepped out for the annual awards show in Los Angeles on Sunday, with stars like Scarlett Johansson turning heads in a plunging Armani Privé gown, Jennifer Lopez dripping in over $9 million worth of Harry Winston diamonds and Jennifer Garner wowing in a red Dolce & Gabbana dress to mark her first SAG Awards appearance in six years.

While we couldn't get enough of their gorgeous gowns, we also noticed another red carpet trend -- powerful, jaw-dropping pantsuits! Now, ET's breaking down all the best menswear-inspired ensembles.

Millie Bobby Brown was one of the first to hit the red carpet, wowing in a custom white silk taffeta coat dress and pants, brooch and satin pumps by Louis Vuitton. The Stranger Things star completed the look with a stunning diamond necklace and ring by Cartier.

Her co-star, Maya Hawke, followed suit, stepping out in a strapless Giambattista Valli number. She accessorized with silver-embellished heels and Swarovski jewelry.

Once Upon a Time in Hollywood star Margaret Qualley rocked head-to-toe Chanel, consisting of a shimmering suit with floral pins. She topped off the look with edgy winged eyeliner and a pink pout, pulling her brunette locks into a low ponytail.

Meanwhile, Qualley's 10-year-old OUATIH co-star, Julia Butters, was proving she's on her way to becoming the next "It" girl. The young actress slayed in a silver sequin Dsquared2 suit, which she paired with a tiny bag by Dan Life.

Big Little Lies star Chloe Coleman also sported a chic boy-meets-girl ensemble. The 11-year-old actress opted for a navy blue Burberry suit and matching loafers, giving the overall look a feminine touch with pretty pearl hair accessories.
