The actress put up a confident stance despite the slit, which opened up further after a model accidentally stepped on her dress.
However, that didn't deter the confident actress from flashing a million dollar smile.
She wore a black dress with a neckline plunging enough to give a clear view of a 22 carat gold choker in an antique finish.
The "Rockstar" actress had already done her catwalk before the 'oops' moment happened.
After the show, Nargis told reporters she just laughed off the incident.
"Nothing happened. Someone just stepped on my dress and I started laughing. I laugh a lot when I am nervous," she said.
During the show, models sauntered the ramp wearing elaborate ornaments in gold as part of the brand's wedding collection. The jewels were accentuated with glitzy red carpet ready outfits in white, bold red, lavender and pink.
Nargis apart, the show saw Priya Sachdev and Rohit Bal take to the ramp as showstoppers.
What added to the ambience was singer-model Rachael Verghese, who enthralled the audience with some enticing numbers including Adele's "Skyfall".
