It is largely regarded as one of the most stylish events of the year, and sees the great and good of the fashion world come together for one night only.
But Pharrell Williams' fiancee would have no doubt been left feeling more than a little red-faced on account of her somewhat ungraceful exit from the 2013 Met Ball on Monday night.
Accompanying her rapper beau to the star-studded event at New York City's Metropolitan Museum of Art, the model and designer was dressed to impress in a chic midnight blue jumpsuit.
However, it would seem either one too many glasses of champagne or her towering skyscraper heels became her literal downfall, with the platinum-haired beauty suffering a wardrobe malfunction of epic proportions as she left the prestigious bash.
Emerging from the venue, Helen looked the picture of grace and elegance as she held on to her man's hand tenderly.
But within seconds, her spiked heel became stuck in a cobble, causing her to tumble dramatically to the ground in a blink and you'll miss it moment.
And things were set to go from bad to worse when a burly security guard intervened in the situation.
Although he was attempting to offer a helping hand, he inadvertantly grabbed the material of Helen's jumpsuit and accidentally exposed her right breast.
As the model visibly cringed at the understandably mortifying situation, all cheeky Pharrell could do was look on and giggle at his fiance's misfortune.
And Helen's embarrassment was no doubt exacerbated by the fact that the whole incident was played out in full view of the assembled photographers.
