She's always had an unconventional approach to fashion, so it's little surprise that Rumer Willis was the biggest fashion 'miss' at Paul McCartney's video premiere last night.

The daughter of famous action-movie star Bruce, appeared awkward in the dress as she made her way into the premiere, which was held in Beverly Hills last night.

She lacked the poise to pull off the chic number, instead slouching as she posed on the way into the premiere.

Rumer, 23, accessorised the number with a long black cardigan.

The dress is from Stella McCartney's Winter 2012 collection – a shorter version is available from Stella's online store, priced at 2,754.

It features very similar design features to the one worn by Miranda Kerr, which features swirling patterns cut out of the fabric.

Earlier today Rumer was seen heading out and braving a downpour in Los Angeles.

She was dressed in a pair of dark jeans, a black jacket, a Where's Wally style stripy T-shirt and black boots – plus a red shoulder bag.

The other big talking point at the event was Gwen Stefani, 42, managing to outshine Australian supermodel Miranda, 28.

Gwen looked striking in her Stella McCartney trouser suit, complete with sheer panels around a bustier and see-through portions down both sides of the delicate long-sleeved top.

Miranda showed off her supermodel shape in her dress which boasted a daring wide split along the front of the frock and mesh panels down her left hand side.

Mother-to-be Reese Witherspoon also put in an appearance and didn’t let her pregnancy get in the way of her style as she rocked a black shift dress with cut-out detail on the arms and skirt.

The trio of beauties were certainly not the only stars to attend the star-studded event, Kristen Stewart, Gwyneth Paltrow, Amy Smart and Ginnifer Goodwin were also in attendance.

The man of the moment Sir Paul McCartney walked the red carpet with wife Nancy Shevell and the couple opted for more casual outfits compared to their guests.

The former Beatle, 69, looked dapper in a smart navy suit jacket which he had teamed with a denim shirt and jeans.

Meanwhile Nancy looked beautiful in bright blue and dressy clean-cut top with a pendant necklace.
