The bedazzled dress in question was a navy blue number covered in hundreds of sequins and adorned with black ribbons.

The piece was from the designer label's Fall/Winter 1994 Ready-to-Wear collection, designed by Karl Lagerfeld.

As well as her exquisite sartorial offering, Blake's glam was second to none. The mother-of-four's modellesque legs were flawlessly tanned; meanwhile he luscious, trademark blonde locks were styled immaculately with a gentle Hollywood wave.

Blake marks a new chapter

The update came weeks after Blake parted ways with her publicist of 22 years, Leslie Sloane, in September, after her legal battle with It Ends With Us co-star and director Justin Baldoni concluded.

Blake joined forces with Leslie during her stratospheric rise to fame when she starred in Gossip Girl from 2007-2012.

According to Page Six, Leslie is widely credited with helping propel Blake to stardom.

Leslie's company, Vision PR, has since represented some of Hollywood's biggest names, including Katie Holmes, Chris Rock, Uma Thurman, Marlon Wayans, and more.

Blake has since signed with power publicist Kelly Bush Novak, CEO and founder of ID-PR, which was also announced in September.

Under Novak at ID-PR, Blake joined an impressive roster of A-list clients like Christopher Nolan, Lady Gaga, Seth Rogen, Alejandro G. Iñárritu, Ben Stiller, Elliot Page, John Malkovich, Serena Williams, Lena Dunham, Diego Luna, Pamela Adlon and many more.
