For her second red carpet look on Wednesday, Aishwarya picked a white Ralph & Russo dress made up of architectural folds, the bodice sprinkled with black.
She posted a picture of herself gliding down a staircase on the Twitter handle she'd been manning for a day:
This is her dress on its way to being worn:
Aishwarya, now in her 14th appearance at the Cannes Film Festival, wore a teal Elie Saab dress for her first red carpet saunter on May 17.
Sonam Kapoor, for her part, wore blue Ralph & Russo on May 16 and lime-coloured Elie Saab on May 18.
To launch her comeback film Jazbaa at Cannes on May 19, Aishwarya wore claret Oscar de la Renta, a designer already spotted on Croisette rookie Katrina Kaif on the opening day. Katrina wore scarlet Elie Saab for her second outfit.
Aishwarya still has one more high-profile appearance to make at the amfAR Gala on May 21.
