The 34-year-old 'Rockstar' actress, who was the show-stopper for jewellery brand Azva, confidently glided down the runway in a black classic Nikhil Thampi gown but while returning a model stepped on her dress causing the incident.
Nargis regained her composure in no time and covered up the fashion faux pas instantly by the cape of her gown.
"Somebody stepped on my dress and I started laughing and I could not stop laughing. I laugh when I get nervous," she told reporters after the show when asked about the wardrobe malfunction.
The US-born model started her career in Bollywood with the 2011 hit Ranbir Kapoor-starrer 'Rockstar'. The actress, however, did not receive much appreciation for her acting prowess and appeared in small roles in 'Madras Cafe' and 'Main Tera Hero' following her debut.
She was recently seen in an item number with Salman Khan in 'Kick'.
