Christa B. Allen attended the American Red Cross Annual Red Tie Affair in Santa Monica on Saturday evening.

The ‘Revenge’ actress supported the organization in a tea-length Donna Karan Pre-Fall 2012 dress with origami-like folding details on the bust line.

Playing up the dress’ vintage quality, Christa accessorized with a vintage Hermes belt and vintage YSL earrings, both from Decades.

Black Christian Louboutin heels and a gold Judith Leiber clutch and a side swept ponytail completed the look.
