It’s Hollywood’s biggest night, and the stars on the red carpet understood the assignment, showing off bright and elegant styles that echo the importance of the evening. The red carpet became a rainbow Sunday night — from best actress front-runner Jessie Buckley in a bright red and bubblegum pink gown to Barbie Ferreira in a dashing cobalt blue, it appears the stars are ready for spring. There was also no shortage of glitz and glam typical of an Oscars red carpet, from the stars of “KPop Demon Hunters” draped in sparkles to Heidi Klum, who was wearing a pearlescent beaded number. Emma Stone joined the trend, choosing a sparkly white short-sleeved gown. Elle Fanning looked beautifully bridal in a white tulle gown, and “Heated Rivalry” hottie Hudson Williams stunned with an early appearance on the red carpet in all black.
