It is the perilous risk of any fashionista’s al fresco outings.

And Ashley James suffered a ‘Marilyn moment’ as she headed into One Horse Guards Avenue in London to attend the launch of Magnum’s latest ice-cream on Wednesday.

The 27-year-old former Made In Chelsea star looked simply sensational for the soiree, hosted by Suki Waterhouse, yet she suffered a near wardrobe malfunction in her tiny mini skirt.

Ashley looked stunning in a bold ensemble yet the weather got the best of her, leading to a moment akin to Marilyn Monroe in the 1955 film The Seven Year Itch where her dress famously blew in the air.

Ashley, who is set to run London Marathon on Sunday, showed off the lean physique she has gained since she started training for the gruelling race.
