Rose Byrne hosted a party in Los Angeles to promote the launch of Australian fashion brand Zimmermann's resort collection. She wore a white and beige paneled dress by the label that featured delicate cutouts and embroidery at the neckline, and a pair of white lacy Nicholas Kirkwood heels.

Does this dress fall on the right side of floaty, or does it swallow Rose just a bit? And does her tightly coiffed updo compete with the ethereal vibe of the outfit?
