Blake Lively and Gabrielle Union steal the spotlight at the launch of Pharrell Williams’ Tiffany Titan jewelry line, with Lively exuding mermaid-chic vibes in a teal dress and Union flaunting her endless legs.

Blake Lively and Gabrielle Union showed off contrasting elegant looks as they arrived at the all-star launch of Pharrell Williams’ new Tiffany & Co. jewelry line, Tiffany Titan, in New York City on Thursday.

The 36-year-old Gossip Girl star glowed in a teal dress that made her look like a mermaid venturing onto land thanks to its scale-like texture, while the 51-year-old Bring It On actress put her long, toned legs on display with a barely there black mini skirt.

The leading ladies were joined by other stars, including The Bear’s Ayo Edebiri, A$AP Rocky and Anitta, as well as the man of the hour, Pharrell.

The event, which was held at the Tiffany & Co. Landmark store, appeared to eschew a traditional red carpet, but that didn’t stop the guests from looking glamorous.

Blake — who was recently announced to return for a sequel to her crime comedy hit A Simple Favor — arrived at the launch in a gorgeous sleeveless teal dress that hugged her curves and emphasized her hourglass figure.
