Worst Hair Of The Week! Keira Knightley's Ponytail Is Gone With The Wind At The Premiere Of Laggies!

It’s a good thing Keira Knightley didn’t blow away!
The wind wreaked a bit of havoc on the red carpet at the Toronto International Film Festival premiere of Laggies, but the actress remained composed.
Unfortunately, her tousled ponytail didn’t make it!
Despite the unwanted mane makeover, Keira looked gorge in a navy, embellished custom Michael Van Der Ham gown, featuring a cool, tulle overlay skirt.
She styled the frock with simple black pumps and a touch of understated, pearl jewelry. Not bad, right??
