Blake Lively wore something you would never expect under her breathtaking cut-out dress

The dress - and this secret detail - are iconic. 

Blake Lively nearly broke the internet when photos of her surfaced rocking a shimmery pink gown with strappy cutouts to a premiere last night, but there was a hidden detail she shared with fans on Wednesday that no one saw coming.

The Gossip Girl alum uploaded a photo in her Instagram Story that showed her lifting up her stunning Prabal Gurung dress with a smile in a garage outside of the Free Guy premiere in New York City, revealing a pair of pink high top Converse sneakers she was wearing on her feet.

Blake’s dress was floor-length and covered her shoes, so it wasn’t clear at what point she slipped them on, especially since she tagged Christian Louboutin as her shoe designer on a photo of her dress. But, we loved the relatable moment nevertheless.

While the actress' backless sequined dress was the clear standout of her look, there were so many other whimsical hidden details that Blake revealed in her Story.

In one photo, Blake showed off her floral-tipped nails and breathtaking diamond rings, and a dazzling gem-encrusted, star-shaped clutch she was palming. She captioned the snap, "Can we talk about @enamelle and these pressed flowers nails plz."

In another, the star revealed a closer look at her braided ponytail, which was wrapped in bling in the form of diamond-embossed Lorraine Schwartz chains. "Diamond pony. That’s also my stage name," she captioned a mirror selfie showing off the look.

"Thank you to everyone who made my prom night 2021 possible," She captioned another photo of herself on the red carpet. 

Although Blake looked like she was the headliner of the film, she was actually on hand to celebrate her husband Ryan’s movie. He stars in the sci-fi comedy flick with Killing Eve star Jodie Comer, Lil Rel Howery, and Taika Waititi.
