Just five nights before the 97th Oscars, the Academy hosted a gathering at its museum in place of the traditional Oscar Nominees Luncheon, which was canceled in the wake of the Los Angeles wildfires.

Timothee Chalamet, Ariana Grande, Demi Moore and other Oscar nominees celebrated on Tuesday at a film academy dinner that gave the contenders a chance to mingle before Sunday's red-carpet awards show.

Celebs arrived in their best fashion attire. Here's a look at what they wore at the awards: Timothee Chalamet looked dapper in a sleek custom designer suit that showcased his signature bold fashion sense.
