Actress and former beauty queen Aishwarya Rai Bachchan made a colourful statement with a dramatic 'butterfly' gown by Dubai-based designer Michael Cinco for her first red carpet appearance at the 71st Cannes Film Festival on Saturday. Aishwarya, who clocks her 17th year at the film jamboree this time as L'Oreal Paris brand ambassador, took a confident walk with the exquisite three meter train trailing behind and catching the attention of the crowd. Aishwarya was welcomed with a loud cheer from the crowd. She waved out and signed autographs, apart from gesturing the traditional Indian 'namaste'.
