Olesya Rulin steps out in a fun strapless dress at the premiere of her upcoming flick, Expecting Mary, held at the Crosby Street Hotel in NYC on Monday night (August 23).

The 24-year-old actress plays the title character, Mary, who was raised with all the trappings of an upscale life. Its only when she finds herself in a small New Mexico town, in a downtrodden trailer park, that she learns the real meaning of love, sacrifice and family.

Also pictured below are her costars Della Reese and Linda Gray.

Olesya will be returning as Abby in Greek on ABC Family later this fall.
