Anna Wintour's face says it all as she shares front row with upstarts Pixie Geldof and Alexa Chung at London Fashion Week

She's spent almost 40 years in fashion journalism and for the past 21 years has held the title of editor in chief at American Vogue.

Having made the journey across the Atlantic for the first time since 2007 to attend London Fashion Week, the high priestess of couture could be forgiven for feeling a little put out at the seating arrangements..

The fashion queen did little to hide her disdain as she perched alongside Alexa Chung and Pixie Geldof at Sienna Miller and sister Savannah'sTwenty8Twelve fashion show.

Not impressed: She was at the Twenty8Twelve catwalk show, the label owned by Sienna Miller and sister Savannah

With her legs inclined away from the duo, who larked around hugging each other, Wintour looked straight ahead with her face fixed in a steely glare and her sunglasses firmly in place.

Meanwhile MTV presenter Chung, 25, and Pixie, 19, pulled faces at each other, possibly feeling a little out of their depth sat next to the hard-nosed fashionista.

The previous day, while Pixie was modelling clothes on the catwalk at the Vivienne Westwood show, Alexa had tried to distract her friend as she watched on.

For goodness sake: Alexa and Pixie break with front row etiquette by larking around and hugging each other

A spectator at the event said: 'Alexa was pulling faces and forming two fingers to try to distract Pixie.

'The next time Pixie appeared in the show she discreetly posed with her two middle fingers up - but with a big grin on her face.'

Wintour was front row at the Twenty8Twelve show tonight, the label owned by actress Sienna Miller and her sister Savannah.

Savannah, a professional fashion designer, launched the brand with her sister in September 2007.

Meanwhile, Wintour has recently featured in a behind the scenes drama that follows her creating the September 2007 edition of Vogue.

The issue ended up weighing nearly five pounds, was 840 pages, and was the single largest issue of a magazine ever published.
