Rebecca Hall dazzled in a black gown at Venice Film Festival 2017 red carpet with her husband Morgan Spector, on Saturday (September 2) in Venice, Italy. Rebecca Hall black dress was a floor length formal evening prom gown, featuring column/ sheath silhouette, with spaghetti straps, and a thigh slit at the skirt, which accented with a bejewelled belt. Rebecca Hall black dress was gorgeous, this is a flawless look. Absolutely love everything about this. Simple, classic, perfection.
