Millie Mackintosh, 32, posed for photographs obviously feeling confident in the get-up as she pouted up a storm.
The gusts of wind soon left her red-faced as she was forced to stop the Sass and Bide gown flying up to reveal her under garments.
Although she took it in good jest as she laughed and ensured Millie Mackintosh held the dress down in front of the many stunned snappers.
The make-up artist teamed her daring dress with a pair of Christian Louboutin high-heeled sandals and carried a Swarovski clutch.
Millie Mackintosh, who is engaged to marry rapper Professor Green, had spent hours on Sunday getting ready for the appearance.
She shared numerous photos with her online fans on Twitter and Instagram as she sat in the make-up chair.
But Millie Mackintosh was clearly nervous as she prepared to step out of the car and in front of the paparazzi.
She complained: “Loving my hair and make up, can’t believe it’s raining! Here I go… Eeeeek #baftas2013.”
And fast forward a little while and Millie Mackintosh took to Twitter again to comment on the embarrassing scenario: “Wind and rain + a dress with slits = wardrobe malfunction!”
She was soon left smiling once more as Made In Chelsea picked up the gong for Reality and Constructed Factual show.
