Julianne Moore's Oscars dress took 987 hours to make.
The 'Still Alice' star - who picked up the Best Actress gong at the ceremony for her portrayal of Dr. Alice Howland in the drama film - wore a custom Chanel gown for the awards show, which featured some intricate detailing.
Speaking on the red carpet, she said: "Karl Lagerfeld made this for me."
The luxury fashion label also revealed it took 27 workers to perfect the dress, which featured 80,000 "small white hand-painted resin sequins and flowers made of ivory, beige and black organza, tulle and sequins."
Meanwhile, Julianne recently revealed she gets style advice from her 12-year-old daughter, Liv, who she has with husband Bart Freundlich.
The 54-year-old actress - who also has 17-year-old Caleb - shared: "[My daughter] always has an opinion. She liked this. She saw me before I left. She's like, 'I like that mama, yeah!"
Julianne also admitted to trying a juice cleanse before an award ceremony previously to lose weight but has since swapped the diet fad for drinking more water.
She said: "I did a juice cleanse for the Golden Globes one year. I think I did it for three days. To be honest, the only weight I lost was in my brain!
"Everyone says it, but I drink a lot of water. I also can really tell the next day when I eat too much sodium so I try to avoid it."
