Diane can thank Bridget Brager for the actress' slicked-back hair, which perfectly complemented the dress.
Not only was the cape draped to perfection, but her red Judith Leiber clutch was in perfect contrast to the black dress.
The cape perfectly graced Diane's shoulders and continued to do so throughout the night.
The cape never lost its volume.
The beaded trim and midriff cutout, along with the actress' Fred Leighton Jewels, made this dress a stunner.
Even in the press room, the cape stood strong.
