In fact, this extraordinary English actress was one of the first to ever take such a sartorial chance by not wearing sky-high heels on this huge event's fashion runway in front of the Shrine Auditorium in Los Angeles.
But the "Saving Mr. Banks" star wasn't having it after having to take off her stiletto Louboutins (her feet were said to be bleeding) and carry them while presenting at the Golden Globes less than a week ago.
Emma Thompson in her flat Christian Louboutin sandals and black embellished vintage frock shared the red carpet with dozens of her actor colleagues.
One such colleague was Mariah Carey who had on a one shouldered Saint Laurent black gown cut high around the bust showing no cleavage , a departure for this typically daring diva. Mariah also donned a pair of leather gloves that did not cover her fingers.
At the same time, Kate Blanchett was looking amazing in her stunning Givency gown that was both sophisticated, fashion forward, and understated.
And so, as Emma Thompson wears flats and a vintage gown to the SAG Awards, she and her many colleagues were dressed to impress yet to be comfortable and onto new trends, too, as the long Hollywood night wears on.
