In July, Robbie made her first appearance since news broke that she was expecting her first baby, attending Wimbledon with Ackerley, also 34.

The actress looked stylish in a black and white polka dot dress that featured a shawl-like left sleeve and an asymmetrical skirt.

She paired the outfit with a black and white bowling-style bag and added some extra height with a pair of open-toe black mules.

Since then, Robbie has been seen sporting several fashionable maternity looks, including a monochromatic white look in Santa Monica and a sheer black look while out and about in Los Angeles.
