Jennifer Garner is a vision in a white off-the-shoulder dress at charity event for the St. Helena Hospital Foundation

Jennifer Garner was a vision in white as she attended the Rockout Knockout Cancer event on Thursday night by St. Helena Hospital Foundation.

The Alias star, 51, showed off her sculpted body in an off-the-shoulder dress that stopped just before her ankle. 

The second annual event was held at the Charter Oak Restaurant and attended by qa number of A-listers.

Her dress cinched at the waist and had a double layer that delivered vintage nostalgia.  

Jennifer wore her cropped hair in a face-framing style and opted for minimal makeup.
