Lily Collins proved once and for all that she is the ultimate leading lady as she turned up to the LA premiere of new movie The Mortal Instruments: City of Bones in show-stopping red carpet style.

Her white, cutaway gown is courtesy of Cushnie et Ochs, a favoured red carpet fashion brand of late having also dressed Selena Gomez in a slinky forest-green dress for the Teen Choice Awards 2013.

Lily Collins worked the daring yet elegant dress with pristine white Giuseppe Zanotti heels, contrasted with dramatic dark plum lips, burgundy nails and her glossy dark chocolate hair for a modern take on a romantically-gothic beauty style. Keeping accessories simple, the Mirror Mirror star opted for diamond stud earrings and plenty of stacking rings on all fingers.

Having been seriously impressing with her style parade of late, it's not surprising that Lily is ahead of the fashion curve - with her two other co-stars also turning up to the star-studded evening working the monochrome trend.

Bella Thorne took a turn on the red carpet working a black and white stained glass print mini dress from Alexander McQueen, playing up her flaxen red hair worn in a loose side plait, while former Twilight star Ashley Greene looked similarly gorgeous in a white Temperley mini dress with stud detailing and sky high nude heels.
