Actor Rahul Bose, Ritesh Deshmukh and Suchitra Pillai were seated in the front row, adding more glamour to the show. With her collection titled 'Life's A Journey', Mahtani launched her men's line as well.
Kelly, looking debonair in a black suit and a white shirt with red piping and carrying a big black bag, kicked off the show.
"I have been prodding Nandita since long to come up with her men's collection as well. And what can be better than me opening the line for her. It is such an honour for me," Kelly told after the show.
"The show was just fabulous, the outfits were stunning but very wearable. As it is her first men's wear line it was just great," he added.
Commenting on her line, Mahtani said: "My collection was inspired by tribal Africa, Morocco, France and India. Basically it is a classic collection but with a little bit of twist and turns."
On the offer were kaftan dresses, halter dresses teamed with slacks, cowl necked dresses, jackets, tube dresses, tube tops, straight skirts, drape dresses, parallel pants, corset tops, racer back tops, long gowns, dresses with asymmetrical hemlines, trench coat dresses and tassel dresses in the women's line.
The men's wear line had bandbox jackets, sherwanis, suits, sweaters, cut sleeve jackets, trousers, shirts and check jackets.
"I wanted to take some time before I launch my men's line so it took a little while before I launched it," she said.
The colour palette remained restricted to beige, white, blue, red and black. There were a lot of laheriya prints in the line.
Fabrics used were brocade, satin, georgette and wool. Beadwork, batik, mirror work and sequins were used to embellish the garments.
The five-day fashion fete, being held at the National Centre for the Performing Arts (NCPA), ends on April 2.
