Shes a fashion icon and the epitome of feminine grace but actress Keira Knightly confesses she still cant wear high heels.

The Atonement beauty made the surprising confession to Glamour magazine, adding shes envious of any girl who can sport a stiletto with confidence.

She says: "I cant walk in heels. Im always so impressed when a woman can walk in heels."

Keira also admits shes not very good at putting together designer wardrobes, because the price tags often leave her reeling.

"As far as expensive stuff goes, Im not good at shopping – Im better at cheap stuff," she explains.

"I think as you get more well known, more designers lend you dresses. But you always give them back like Cinderella because you shouldnt be buying them; £20,000 for one night?!"

One celebrity who certainly wont share the actress opinions is Spice Girl-turned-LA trendsetter Victoria Beckham – the Daily Mail recently reported she feels brainier in designer heels and simply cant concentrate in flats!
