The Academy Awards mark the grand finale of what has been a highly politically-charged awards season thanks to the #MeToo and Time's Up movements.
As Hollywood’s major players respond to the myriad sexual misconduct allegations sweeping through their industry, the red carpet has seen a seismic shift in cultural and sartorial significance.
However, while attendees were encouraged to come together in protest via all-black ensembles at the Golden Globes and the Baftas , no such dress code was issued at this year’s Oscars.
Instead, organisers advocated style autonomy while Time's Up founders stood down in a bid to illustrate that the importance of the initiative transcends beyond the red carpet.
From Margot Robbie channelling Grecian glamour in custom Chanel to Viola Davis packing a punch in Barbie doll pink, click through the gallery below to see the best-dressed stars at the 90th Academy Awards.
