The actress was demurely pretty in a blue plisse Chloe dress with embellished panels along the neckline and an asymmetrical hem.
The dress's plunging v-neckline showed off some cleavage, but Zoe's flat-ironed locks tended to cover it up.
Overall, the look borders on plain, but maybe that's because her diamond engagement ring was nowhere to be seen! Instead, she blinged out with a Rona Pfeiffer ribbon ring and EF Collection earrings.
Kinda strange considering she was wearing it the day before while out and about with hubby Marco Perego in Venice.
What gives Zoe?
