All eyes were on Jessica Biel at Tiffany & Co.'s Blue Book Gala in New York City Thursday.
The actress turned heads wearing a cleavage-baring Oscar de la Renta gown from the Fall 2014 collection. Biel, 32, accessorized with a diamond-drop platinum necklace and a silver-metal waistband. She completed her look with a black-and-white Oscar de la Renta Goa clutch and simple black pumps.
"It's incredible," the Total Recall star said of her Blue Book Collection necklace. "It feels like it could be from another time. It's modern now and it could have been modern 100 years ago. It has that feeling to me."
Biel took a few selfies at the Guggenheim Museum, as did fellow celebrity guest Katie Holmes. Like Biel, she looked sophisticated and sexy wearing a black Balenciaga mini with a white, layered skirt. The Dawson's Creek star paired it with Manolo Blahnik pumps and, of course, selected Tiffany & Co. jewels.
The brunette beauties bonded inside the star-studded event with another A-lister, Kate Bosworth, who looked divine in a pink foiled-silk-wool strapless gown from Katie Ermilio's Fall 2014 collection. The Still Alice actress added extra glamour with Tiffany & Co. jewels and mirrored Rauwolf clutch.
Other attendees included Sean Avery, Seth Meyers, Michael Polish and Hilary Rhoda.
Biel's husband, Justin Timberlake, was nowhere in sight. The actress had just returned from England after joining the "Not a Bad Thing" singer for the European leg of his 20/20 Experience World Tour.
