As the end of the Oscars drew close, the anti-bullying activist popped up at Vanity Fair‘s annual bash in L.A. Sunday.
Lewinsky, 42, donned a simple strapless black dress featuring tiered ruffles. She styled her hair up and completed the look with red lipstick and sparkling earrings.
The appearance comes nearly three weeks after Lewinsky joined forces with Vodafone to create and debut the new #BeStrong Emoji Keyboard app, which help teenagers “communicate support in a bullying situation.”
“Had social media been around in 1998, the thought of the hashtags alone makes me want to run to a therapy session,” she told PEOPLE exclusively. “But what would have been positive was that not only would I have been able to see when someone made a supportive comment, but others would have, too. Compassion can be contagious.”
She added: “That is what is at the heart of the #BeStrong emojis: for people – especially teens – to feel less alone when these incidents happen online.”
The 88th annual Oscars, hosted by Chris Rock, are being presented live on ABC from the Dolby Theatre in Hollywood, California.
