Margot Robbie at Charles Finch and Chanel Pre-Oscars Dinner

The event is almost as exclusive and coveted as an invitation to the Academy Awards themselves.

And the stars shone at the Charles Finch and Chanel Pre-Oscars Dinner at the Beverly Hills Hotel’s Polo Lounge on Saturday night, led by Margot Robbie, Demi Moore, and Diane Kruger.

Robbie wowed in yet another stunning look, a strapless black column dress that was evocative of a double-breasted suit jacket or coat.

Margot, 29, is currently in the midst of a particularly busy time as she makes the rounds in support of this weekend’s major studio release Birds Of Prey.

Joining Margot was another influential and fashionable star, Demi Moore.

Demi, 57, looked incredibly stylish and sexy in her tweed pantsuit look, which featured a sports jacket with no shirt but her black bra peeking through.

The pattern of her suit was a plaid in black, white and blue stripes, and her slacks were ultra wide in the legs.
