Blake Lively's Blue Sequined Look

Blake Lively was out at the grand opening of the Marquee Nightclub in Las Vegas with singer Florence Welch on December 30.

Blake was in a simple black button-down shirt but turned her outfit into a real stand-out, teaming with blue sequin Isabel Marant pants.

Both were in Louboutin booties; Blake in the low-cut Miss Fast Booties, and Florence in a button-detailed pair.

The Marant pants have also been seen on Jessica Alba.  She wore them for a photoshoot last year.
