Mandy Moore stole the show at the premiere of her new movie "47 Meters Down" on Monday night in a bronze, silk gown that she rocked -- sans bra! The 33-year-old actress' slinky number left little to the imagination as it clung onto every inch of her curvaceous figure.
The "This Is Us" star left the rest of her look pretty simple, choosing to only accessorize with a sea foam green ring. She kept her brunette tresses in beach waves while keeping her makeup to a minimum.
This is just the latest in a string of show-stopping looks from Moore in the past couple of weeks. She dazzled in a bold, leopard-print frock at the CFDA Fashion Awards just last week.
In the movie, Moore plays Lisa, a woman who goes shark diving in Mexico with her sister. Their worst fears soon become a reality when the cage breaks away from their boat, sending them plummeting to the ocean floor with a dwindling supply of oxygen.
Claire Holt plays Moore's sister in the movie. The actress, known for her role in "The Vampire Diaries," also dazzled at the premiere in a red, beaded mini dress. She paired the long-sleeved number with a pair of nude stilettos that elongated her toned pins.
Moore couldn't stop gushing about her co-star on the red carpet, calling her "a beacon of light and goodness."
"I feel so incredibly lucky that I got to make this film with her," she revealed to ET. "She had my back and I tried to have her back and I feel like we were able to get through this experience because we had one another."
"47 Meters Down" hits theaters June 16.
