Sonam opted for a Vera Wang couture gown while attending the red carpet for Hollywood movie Solo: A Star Wars Story.
As Sonam walked along, the long train of her dress - hued in beige and yellow - followed around gracefully.
This was Sonam's second red carpet appearance at Cannes this year.
On Monday, the actress sashayed down the aisle in an embellished lehenga, hand-picked from the studious of Ralph and Russo.
This is Sonam's first international visit after she married Anand Ahuja on May 8. Her wedding was followed by a big fat reception, which was attended by most of the Bollywood celebrities.
