As the Duchess of Cambridge knows only too well, windy weather is one of the prime causes of wardrobe malfunctions.

But 'gale fail' as it has been nicknamed could soon be a thing of the past if one British department store gets its way.

Debenhams is to temporarily introduce wind machines to its flagship store so customers can put their floaty dresses on trial before purchase.

Debenhams has installed a wind tunnel in-store to allow party goers to see if their outfit is prone to gale fail

Those looking for the perfect wedding or Ascot frock will be able to put them to the test at the Oxford Street store over the bank holiday weekend.

Special industrial fans which can be adjusted to mimic a gentle breeze or a full-blown 40 mph gale have been set up in the fitting area and cost nothing for shoppers to use.

Personal stylists will also be on hand to advise customers on which garments are best for beating gale fail, from the right head-gear to skirts, dresses and even footwear.

Speaking about the wind tunnel, Alain Mehada, the head of styling at the Oxford Street store, says he hopes customers will take the opportunity to wind test their summer ensembles.

'It can ruin a special day when someone has spent a long time choosing what to wear, only to find themselves battling with the wind, holding on to their hat with one hand and the hem of their skirt with the other, while teetering in skyscraper heels,' he says.

'A big part of many summer events, particularly weddings and big race meetings such as Ascot, is wearing a special outfit that makes you feel confident that you look your best, but relaxed enough to enjoy the day.

'It is very difficult to do that if you are worried about your dress flying up to reveal more than you bargained for, or your lovely new hat soaring off into the distance.'
