A look at the stars who made bad style choices this week...

We start off this week’s celebrity fashion disasters with Lena Dunham, who no longer looks like one of the Girls but more like a granny in this bulky, belted dress that ages her about 30 years at the Venice Film Festival on 28 August.

At the same event is grande dame of French cinema Catherine Deneuve, wearing a full-length frock that does her no favours.

But save your fashion pity for Charlotte Gainsbourg, also in Venice, whose seamstress seems to have forgotten to finish off her outfit.

Meanwhile Sheridan Smith gives us plenty to ponder with her nasty netted dress and Nurse Jackie actress Edie Falco blinds us with her golden get-up and matching tan. Kelly Bensimon from the Real Housewives of New York City also gets in on the golden game with a pair of shiny knickerbockers.

Former child actress Abigail Breslin demonstrates what happens when body-con goes bad and Chloe Sevigny revisits the 70s in a pale pink safari suit.

And finally there’s Rihanna, who’s usually used to wearing very little but seems to have missed the mark here by stepping out in something her tailor hadn’t quite finishedÂ…

What were they all thinking?
