Lively and Reynolds looked like the perfect pair at the 2014 Cannes Film Festival.
Lively's strapless gown had a black base with a white trim. A white train flowed around the gown, creating a three-dimensional look.
She accented the dress with a diamond choker, earrings, and cuff, which she showed off with her hair in a low bun.
Reynolds looked sleek in a black tuxedo paired with a white shirt and white bow tie.
