Her Met Gala gown reportedly took 600 hours to make.
And Blake Lively, 30, took to Instagram on Friday to reveal that there was a hidden message to her opulent red carpet look.
Taking into consideration the Heavenly Bodies: Fashion and the Catholic Imagination, the actress’ gown was complemented with a clutch, which featured a cross which had the initials of all members of her family on each point.
The gold cross detailing featured four letters – a ‘B’ for herself, ‘R’ for husband Ryan Reynolds, J for 3-year-old daughter James, and I for 1-year-old daughter Ines.
Blake’s shadow was present in the snap as she leaned in to take the snap of the design – which was missed by many on the red carpet.
‘Take your family to work day,’ the former Gossip Girl actress captioned the stylish snap.
On Monday, Blake pulled out all the stops as she stepped out onto the red carpet of the 72nd annual Metropolitan Museum of Art Costume Institute benefit.
The star showed off her killer figure wearing a gilded bodice with a sheer-panelled crimson skirt.
The top of her ornate gown was woven with gold thread among a host of ruby and emerald jewels, with an ample amount of cleavage on display.
‘This year’s may be my favourite dress ever,’ Lively shared to Vogue earlier this week. ‘They’ve already worked on it for 600 hours, and it’s not done.’
Meanwhile, as well as pictures from the Met Gala, Blake has been littering her Instagram platform with a plethora of snaps after she recently returned to Instagram.
Blake’s Instagram stunt was part of a viral campaign ahead of the release of her new thriller A Simple Favor.
The movie, directed by Paul Feig, is based on Darcey Bell’s novel and follows a vlogger named Stephanie (Anna Kendrick) who goes on the hunt to find the truth behind the disappearance of her best friend Emily Nelson, played by Blake.
Before her account clear out, Blake’s last, now-deleted, post was a photo of a completed game of hangman, the answer to which was: ‘What happened to Emily?’
A Simple Favor is scheduled for release on September 14.
