Call it the perfect ponytail. Saldana's undone waves create a laid-back vibe, while the added volume at the crown gives the style a retro twist. "Zoe wore a gorgeous lace Elie Saab dress to her premiere of The Words. We discussed her look, and decided on a sexy, effortless low pony," said Saldana's hairstylist Mara Roszak. "I created the perfect wavy texture by loosely braiding sections and allowed them to air-dry."
