On Monday, the 46-year-old "True Detective" actress attended the 2022 Toronto International Film Festival to celebrate the premiere of her latest project, "Nanny" — an American horror film directed by independent filmmaker Nikyatu Jusu.
The brunette bombshell walked the red carpet in a daring yet elegant chainmail gown with black leather detailing. She paired the dress with a pair of dainty silver earrings, black stiletto heels and smokey eye makeup with light pink lipstick.
Earlier in the day, the "Echoes" star took to Instagram to share another TIFF look — a stunning black and white houndstooth pantsuit by Versace, which she paired with black high heels. She wore her hair in a dramatic side part with big, tousled curls — and opted for a natural-glam makeup look.
"Here we go," she captioned the photo for her more than one million followers.
Fans met Monaghan's photo with praise for her classy and distinguished second look.
"Loved both of your looks tonight! The dress and the suit are so gorgeous, and so are you," one Instagram user commented, while another added, "So gorgeous!"
"This suit is everything. Go off, boss queen!" someone else penned.
One fan commented: "So pretty!"
"Stunner!" another chimed in, while someone else wrote, "I love houndstooth. What an amazing pattern!"
"Class and beauty is definitely your hallmark," commented another.
One person added: "Glamorous and chic!" and another, "So classy."
Monaghan shared additional photos via her Instagram story showing off her pantsuit and gorgeous locks.
"The hair that keeps on giving," she wrote over a video selfie, crediting her hairstylist and colourist, Marilisa Sears and Christopher Pierce.
"Nanny" premiered at the Sundance Film Festival earlier this year, and hits theatres in November.
