When it came to packing for Cannes [1], Blake Lively [2] thought about every occasion clearly — from touching down at the airport [3] to playing dress-up [4] in her hotel room. So we're not surprised she's pulled out all the stops for her first official appearance — a photocall [5] for her new Woody Allen [6] film Café Society.

Blake showed off her growing baby bump [7] from all angles in her Juan Carlos Obando jumpsuit, which she paired with metallic Christian Louboutin heels, but it was her Jennifer Meyer jewels that made us do a double take. Though Blake's red silhouette came complete with a ribbon that draped like a choker, she still wore a dainty gold chain too. Read on to see Blake prove there's no such thing as a necklace too many, and check out the sneak peek she 'grammed [8] of her look.
