We haven’t seen much of Lynn Collins lately, but the actress was on the red carpet tonight for the London premiere of her latest movie, ‘John Carter’.

A big premiere needs a show-stopping gown, so she glided down the red carpet wearing a sultry number by Antonio Berardi.

Her Spring 2012 sexy silk chiffon gown with leather embroidery was styled with romantic waves à la Veronica Lake and hot red lips to give her look an authentic old Hollywood vibe.

This is the perfect way to kick start a promo tour.

Van Cleef & Arpels’ jewels completed her look.
