The 32-year-old actress, who is nominated for Best Performance by an Actress in a Supporting Role in a Series, Limited Series or Motion Picture made for Television - Drama for her role on This Is Us, turned heads at the 74th Annual Golden Globes at the Beverly Hilton Hotel in Los Angeles on Sunday, donning a gorgeous sheer gown.
The risqué dress, designed by Naeem Khan, featured a plunging neckline that left very little to the imagination.
The brunette beauty completed her look with stunning teardrop earrings, a diamond bracelet and sapphire blue clutch.
When ET caught up with Moore on the carpet, she told us this was the second dress she tried on during her fitting.
"I've always wanted to wear a cape," she exclaimed. "I feel like a quasi-superhero."
And a beautiful one at that!
