Wearing an off-white lehenga choli and heavy kundan jewellery, the 28 year old walked very casually to the hit song Senorita from the film before she started dancing, instilling energy into the show and leaving the audience asking for more.
Koechlin's dance moves made even the other models shake a leg.
"I was quite nervous before I came onto the ramp, but when I heard the song, all my nervousness went away. I would really say that acting is much easier than ramp walking, because till the time you don't finish the walk there is so much pressure that it is nerve-wrecking," the actress said.
Asked what her favourite piece of jewellery was, Koechlin, who recently married filmmaker Anurag Kashyap, said: "My wedding ring is very precious to me because it's my grandmother's wedding ring that has been passed down to me."
However, Koechlin, who made her debut in Bollywood with Dev D. added that she isn't too much into jewellery. "I don't wear much jewellery, because my clothes are usually casual, so it doesn't go with that."
