Buffy famously wore the white gown to take on The Master in the hit show's season 1 finale. Though he drowns the Slayer, briefly ending her life, her bestie, Xander (Nicholas Brendon), gives her mouth-to-mouth, bringing her back from the dead to finally defeat her first Big Bad of the series.
This isn't the first time Gellar has referenced her monster-fighting alter ego while in quarantine from the coronavirus. In March, she posted a funny GIF of Buffy wielding a scythe in the show's series finale and another one of her wearing sushi pajamas, writing, "How I expected my apocalypse outfit to look. How it actually looks."
She's also shared several GIFs of Buffy crying, first writing, "Me realizing there is no end to homeschooling in sight. Who feels me?!? (I feel for my kids) #throwbackthursday," and then, "No....no...... homeschooling is going great.... everything is great .... I’m doing great #throwbackthursday#homeschool."
