Best Actress frontrunner Glenn Close channeled an Oscars statue in a regal caped gown, Jennifer Lopez was a total vision in a disco ball-esque column gown, Charlize Theron debuted new brunette locks and Regina King was white-hot in an elegant dress with a thigh-high slit.

The prevailing trend on the red carpet this year, though, was pink, pink and more pink: Gemma Chan, Helen Mirren, Linda Cardellini, Angela Bassett, Sarah Paulson and Marie Kondo were among the famous faces to don the striking color.

There were also a slew of A-list couples on the red carpet, who you can see in the gallery below:
