Jessica Chastain was a totally different woman when she stepped on the red carpet for the 37th Annual Los Angeles Film Critics Association Awards yesterday evening.

She went from ‘ladies who lunch’ at the AFI Awards, to sexy temptress at this event wearing Vivienne Westwood.

Her Fall 2011 Autumn print off-the-shoulder signature Westwood dress perfectly complemented her gorgeous fluffy retro curls.

Nude Jimmy Choo platform strappy sandals completed her look.

The actress is still opting not to carry a clutch.

I feel so lost without something in my hands whilst stepping out.
