There are many things we love about Keira Knightley: her underrated role in "Pride & Prejudice," her cool attitude when it comes to recycling her wedding dress, her amazing Chanel wardrobe and her always gorgeous hair.

Take her recent appearance at the Chanel Fall 2014 show in Paris: the actress' brunette hair was styled in simple waves that curled around her shoulders, giving hope to all us lazy gals. In February, the Brit attended a party rocking messy-chic locks which we know we could duplicate with ease (ie. not brushing). Finally, "The Duchess" star, who turns 29 on March 26, went glam with an elegant updo at the "Jack Ryan: Shadow Recruit" premiere in London.

Still not convinced? Well, Jamie Dornan's ex rocked a pixie cut way before Miley did.

So, in honour of her birthday, we take a look back at our favourite Keira Knightley hairstyles.
