Forty-year-old actress splashes around in the Santa Monica, Calif., waves with her two daughters

Jennifer Garner enjoyed a mother-and-daughter beach day with daughters Violet, 7 and Seraphina, 4 on Sunday at Santa Monica, Calif.

Ben Affleck‘s ladylove kept it casual and comfy while splashing around in the waves with Seraphina.

The 40-year-old actress sported a chambray button-up and jean skirt paired with a sunhat while Seraphina wore an adorable all-pink outfit.

Looks like the girls had a fun outing sans the boys—perhaps dad Ben and the couple’s 13-month-old tot, Samuel, had a boys’ day!
