Leslie Mann rocked quite a different look on the red carpet at Teen Vogue’s 10th Anniversary Young Hollywood party in Beverly Hills, California, on Thursday evening.

She rocked a bold Rodarte Fall 2012 floral dress.

This sleeveless black-and-red floral jacquard A-line dress with a sharp pointed collar is a huge departure from the uber-girlie dresses we are used to seeing from Leslie.

She spoiled me so much with a succession of colourful looks this summer that I’m not sure how I feel about this darker look.

What I do know is I don’t like her clunky Rodarte footwear.

A slicked-back side-parted ponytail and a copper lip colour completed her look.

Yay or nay?
