Case in point, the floor-length Saint Laurent gown the 54-year-old actress sported on Thursday, when she picked up the Best Actress award for her work in the film "Still Alice."
The gorgeous redhead's black dress was simple except for a lace illusion neckline that revealed her decolletage. Earlier this week, Julianne turned heads in a silver ombré Givenchy Couture gown at the 2015 Golden Globes, where she also nabbed the Best Actress award, leaving Aniston empty-handed.
Although we think Julianne is usually flawless, she did make one small snafu during her acceptance speech when she forgot to thank fellow Best Actress nominee Marion Cotillard. Naturally, she apologized via Twitter:
"i forgot to mention #MarionCotillard in my speech tonight and i am mortified," she said of Marion. "She is exquisite in everything + especially in #2days1night."
We love you, Julianne!
