Sienna Miller and Pixie Geldof lead fashion FAUX PAS on the BFAs red carpet, what were they thinking?

Sometimes we really just don’t get fashion.

On a night intended to showcase the best of British style, some stars truly failed to cut the mustard.

Sienna Miller and Pixie Geldof were just two of the celebs to make fashion faux pas at the British Fashion Awards last night.

The 31-year-old fiancé of actor Tom Sturridge showed off her new pastel pink locks on the red carpet – but even that didn’t make up for her style mishap.

The British actress donned a silk, emerald green Burberry gown for the BFAs – but it was poorly fitted and drowned her petite frame.

The mum-of-one opted for quirky accessories, including a silver circle necklace and a bronze box clutch for the awards ceremony – failing to pull together the lacklustre look.

And socialite Pixie Geldof looked equally disastrous on the British Fashion Awards red carpet.

Peaches Geldof’s younger sister, 23, looked like she’d got dressed in the dark as she posed for photographers on the red carpet.

The DJ/model donned a silver negligee style dress for the annual ceremony – teamed with a bonkers green furry teddy handbag. What was she thinking?

A dark berry lip, hoop earrings and brown bob hairstyle completed her look – taking her straight to the top of our worst dressed list.

Model Edie Campbell, Jodie Kidd and Susie Bubble were among the other stars to have a wardrobe mishap last night.
