Blake Lively Suit Pictures at Gaga's Workshop Launch

Blake Lively Sexily Suits Up to Help Launch Gaga's Workshop

Blake Lively looked long and lean in a blue pantsuit.

Blake Lively managed to show some skin in a suit last night at Barneys New York's launch of "Gaga's Workshop." The bright blue Elie Saab look was finished off with lace-embellished shoulders. It was her latest daring look after wearing a revealing Marchesa number Saturday to the Gossip Girl 100-episodes celebration. Blake had the company of her small screen buddy Matthew Settle last night, as well as Neil Patrick Harris, David Burtka, Brad Goreski, and Alexander Wang. We caught a moment with the actress, and Blake Lively shared her holiday must-haves. She told us she's currently buying lots of Chanel and Brunello Cucinelli for the colder weather.

Lady Gaga herself was on hand to celebrate the opening of her holiday collaboration with the iconic department store. Gaga was decked out for the occasion in a white Chanel gown that was customized by Karl Lagerfeld. There are tons of details about Lady Gaga's Barneys workshop — the installation, which takes over the shop's entire fifth floor, included eight shopping stations customized by Gaga and her team. Fans can browse a jewelry nook, a bookstore, and a boudoir that sell over 170 limited-edition Gaga-themed products as well as some of her favorite items from childhood. The store-within-a-store is open now and will be until Jan. 2, 2012.
