The 31-year-old British-Indian beauty, who made her first Cannes red carpet appearance at the prestigious festival, looked gorgeous in the elaborate gown with her side-swept red hair adorning soft curls.
She kept the make-up minimal and completed the look donning a pair of tear drop diamonds earrings and thin diamond bracelet.
The “Fitoor” star attended the premier of the French film “La Tete Haute” (Standing Tall) on the opening day of the festival.
“Hello from the @Festival_Cannes red carpet! #Cannes2015 #LorealParis @LOrealParisIn,” Katrina tweeted along with a picture.
Earlier in the day for media interviews, she opted for a white crop top and skirt with heels by Manolo Blahnik and jewellery by Maria Francesca Pepe.
Katrina also posed with L’Oreal Paris co-ambassador and Hollywood actress Julianne Moore before heading for her debut on the Cannes Film Festival red carpet.
Both the actresses, who also shared a selfie, will be shooting together for the brand today.
Other Indian actresses Sonam Kapoor and Cannes regular Aishwarya Rai will arrive soon at the festival. Sonam, who is making her fifth red carpet appearance, is scheduled to walk the on May 16 and 18, while Aishwarya will make her presence felt at the world’s biggest and oldest film festival on May 17 and 18.
The Festival kicked off last evening with the French drama directed by Emmanuelle Bercot.
