Keira KnightleyKeira KnightleyNow, we don't mind a bit of individualism when it comes to fashion here at Showbiz HQ.

However, we do get a little irked by A-list stars who flout a dress code but get away with it because of who they are.

There are many, many times when we want to go to work in our pyjamas or go out for a swanky meal dressed in our baggy, old trackie bums...

But we don't because etiquette says it's not the thing to do.

So, who does Keira Knightley think she is, popping out to one of London's posher eateries with a scruffy, woolly hat atop her head?

Sure, she made the effort in the dress department with a stylish, strappy, grey number with glam gold belt - but that only highlights the inappropriateness of the beanie hat.

Perhaps she thought it would be a good disguise from the waiting paps, as she and boyfriend Rupert Friend strode into the restaurant.

Or perhaps she's had a bad haircut? A pob gone wrong?

Let's just hope that once inside the swanky nosh hole, she whipped it off sharpish.
