Fashion savvy Sonam Kapoor made her debut on the Cannes red carpet in a Jean Paul Gaultier Spring 2009 couture gown and designers feel that the classic and vintage look suited her well and enhanced her figure.

L'Oreal brand ambassador Sonam attended "The Artist" premiere at the 64th Annual Cannes Interntaional Film Festival May 15 in the form-fitted net gown and teamed it up with Chopard earrings, an Amrapali ring and peep-toe heels by Salvatore Ferragamo.

More than her dress, it was her shapely buttocks that attracted eyeballs. Designer Nil of label Dev R Nil, who designed one of her the dresses for a press conference at Cannes, thinks she made a brave choice in choosing a dress which was different from Indian sensibilities.

"She has gone for a very classic and vintage look. I think it was quite a brave choice considering such an architectural draping and completely non-embroidered gown which was quite contrary to the Indian sensibilities. The gown was beautiful and well-constructed, highlighting her butt. Also her hair-do and make up was kept very minimal keeping in mind her face and bone structure, " Nil told.

"She also wore a one piece shift gown which was very beautiful, and on another occassion, a lovely polka dotted silk sari with a shirt inspired blouse designed by good friend Masaba Gupta. She is a style icon in herself and she proved it once again, " he added.

For designer Arpan Vohra, Sonam scored highest in comparison to her counterparts like Aishwarya Rai and Mallika Sherawat.

"The gown was a couture piece of modern inspired artwork and Sonam looked very chic in it. She is tall and that helps her carry the gown with a long trail with ease. She loves to experiment and here too she scored the highest in comparison to her counterparts, " Vohra told.

The 25-year-old managed to grab eyeballs for revealing her butt in the gown and designer Varija Bajaj says it was because of technical flaw in the gown.

"From a distance I liked her overall bold look which she carried with great style for her first appearance. Technically the outfit was badly finished with raw seams of net and not so twisted hip clutcher. She did her best in choosing the outfit, but the designer should be blamed for the technical faults. She could have also demanded a better finishing from the designer, " said Bajaj.

"If the designer could have used a small hole net than a big hole, it would have looked more graceful. In short, good design and style by the designer, but technically flawed execution, " she added.
