Hilary Swank and Jessica Biel dazzle at Tiffany & Co. flagship opening in Paris

We can hardly think of anything more glamorous than a star-studded opening party for the Tiffany & Co. flagship store on the Champs Elysées in Paris.

Two of Hollywood’s biggest stars, Jessica Biel and Hilary Swank, attended the A-list soirée on June 10, which saw the luxury jewelry retailer open its doors on what is known in French circles as "the most beautiful avenue in the world.”

Looking effortlessly chic in a strapless beige cocktail dress, Jessica wore a string of diamonds around her neck to match her enormous engagement ring, given to her by her husband, Justin Timberlake.

Hilary, meanwhile, was elegant as ever in a black LBD paired with strappy sandals and her long brunette locks worn curled and parted to the side.

After cutting the inaugural blue ribbon, the actresses reportedly headed to the Arc de Triomphe rooftop for the evening’s glittering festivities, where they were joined by a who's who of international stars and tastemakers.

“While we have been successful in operating three smaller stores in Paris, establishing this store on the Champs Elysées will be the ultimate symbol of Tiffany as a truly global luxury brand,” Executive vice president Frederic Cumenal said.

He added: “This is a preeminent location that firmly places Tiffany & Co. on an international stage, in the heart of a city where people from all over the world come to visit and shop.”
