We love Jamie Chung's smart mix of sexy and sweet, like this look from Charlize's Theron Africa Outreach Project cocktail party last night. Her creamy, button-front frock shows a little skin, though we love that it stays on the ladylike side of things. To anchor the dress's summery vibe, she adds a dark leather Proenza Schouler carryall and a pair of olive-toned platforms. A red lip and a few simple gold jewels dress it up just a bit, making a perfectly understated party style. Just shop our editors' picks to channel Jamie's easy-chic vibe.
