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

It’s officially autumn and the start of the season has seen some cracking celebrity worst-dressed efforts.

Kicking things off, repeat offender Jaime Winstone looks nasty in a nylon shirt dress with chunky black boots and novelty glasses at London Fashion Week on 15 September.

Over in LA, Dirty Dancing star Jennifer Grey steps out in a neon nightie and scuffed shoes. At a red carpet event!

She’s not the only one breaking the fashion rules – reporter Billie JD Porter gets creative with Nan’s net curtains and the results aren’t pretty.

Elsewhere, ex-Girls Aloud member Nadine Coyle’s outrageously oversized trousers leave her with a saggy crotch and huge hips.

Worst-dressed isn’t worst-dressed without an Only Way Is Essex contender and this week’s shocker in silver is ex-TOWIE star Sam Faiers in a shiny trouser suit. You can take the girl out of Essex…

Meanwhile, fashion editor Anna Dello Russo is a multicolour mess in her over-the-top outfit.

Mischa Barton is no better in her bright orange coat. Someone’s been Tango’d!

At least Mischa’s wearing something, though, as reality star Aisleyne Horgan-Wallace demonstrates that sometimes more really is better. Well, certainly classier!

Finally, US singer Rydel Lynch takes inspiration from Superman in her underwear-worn-on-the-outside outfit and Rita Ora has a wardrobe malfunction with undone flies.
