Jessica Alba‘s style remains enviable as she prepares to become a mom of three!

The actress and co-founder of The Honest Company announced Monday that she and husband Cash Warren would be giving their daughters Haven Garner, 6 next month, and Honor Marie, 9, a new little sibling.

In the adorable Instagram post, Alba and her mini-mes are holding black “1,” “2” and “3” number balloons while the mom-to-be wears a frill-happy, black McGuire dress with a high-low hemline. The pretty frock — called The Wild Years Off the Shoulder Dress — retails for $215.
