Oscars 2019: Allison Janney, Hilary Swank and Tiffany Haddish are knockouts at Cadillac pre-party

It's Oscars weekend! For Hollywood's biggest names, that means every night's outfit better outdo the next. (For us, it means sweatpants.)

Allison Janney is already setting our expectations high for the Academy Awards on Sunday: Three days before the big night, she hit Cadillac's Oscars pre-party looking incredible in a cleavage-baring crimson jumpsuit by Galvan. Janney, last year's Best Actress winner, will present this year's Best Actor award alongside Gary Oldman.

Meanwhile, Tiffany Haddish rocked a gorgeously crisp white pantsuit by Michael Kors. You can shop her exact blazer here on Nordstrom.

Opting for a more conservative look was Hilary Swank, who wore a high-neck white Emilia Wickstead number with long sleeves. On her arm was husband Philip Schneider, who she wed in April 2018.

Swank and Schneider had some competition for best-looking couple of the night: John Stamos and wife Caitlin McHugh enjoyed a well-deserved night out! The two welcomed their first child, Billy, less than a year ago.

See all the looks in the gallery above.
