Olivia Palermo dazzled in bright colours at London Fashion Week over the weekend.

The American socialite looked gorgeous in an eye-popping orange blazer, charcoal t-shirt and black laser-cut trousers as she graced the Mulberry front row on Sunday.

The fashion icon confirmed once more that she can pull off even the most difficult of looks to perfection as she accessorised her outfit with a pair of blue Manolo Blahniks and simple gold jewellery. Olivia added a twist to her look with a zebra-print Mulberry Alexa handbag.

The socialite was joined by a host of stylish A-Listers including Michelle Williams and Lana Del Rey, who has just been honoured with her very own Mulberry handbag style.

Oscar nominee Michelle looked cute in a light-blue dress which she teamed with a fitted navy coat and studded black heels.

Lana went for a cool casual look in jeans, a white collar-less shirt and a varsity jacket teamed with nude snakeskin ballet pumps.

Vogue editor Anna Wintour and British actor Bill Nighy also took in the label’s latest offerings.

Meanwhile, Christina Hendricks looked elegant and demure in muted colours at Vivienne Westwood’s after show dinner. The actress kept her famous curves under wraps in a black roll-neck jumper, cropped trousers and a simple grey coat following the designer’s Red Label presentation. The beauty added some excitement to the ensemble with a pair of leopard print heels. Her flaming locks had been backcombed into a bouffant half-up, half-down do.

Actress Gemma Arterton and musician Tinie Tempah took their seats in the Issa front row on Saturday. The brunette beauty looked breathtaking in a black lace dress with nude lining and elegant black heels.

Rapper Tinie cut a dash in a sleek black suit and sparkling black shoes with a white fabric rose attached to his lapel.

Meanwhile Rihanna dazzled in a slinky green gown at Stella McCartney’s Winter 2012 London Evening Wear Presentation and dinner in Mayfair.

The singer looked stunning in the full-length dress which featured a low neck- and back-line and a thigh-high split. The Bajan beauty accessorised the look with a gold statement necklace, bangles and strappy sandals.
