Lively shared a carousel of photos showing the stunning Tamara Ralph diamond chainmail minidress she wore teamed with a voluminous, tangerine-orange silk taffeta cape to the LACMA

“ @bazluhrmann was the first & only signed poster I was ever lucky enough to have on my wall when I was a teenager,” Lively wrote alongside a series of pictures of her and Luhrmann during the star-studded gala. “It’s still on my wall today. To know him will always be surreal. He’s even more mischievous and magical in real life.”
