You're About to See This Valentino Dress on All Your Favorite Style Stars

First, Olivia Palermo worked her signature styling magic on this Valentino dress — and we can't say we were surprised by the lovely outcome. But we've got to hand it to the fashion house: the star-embellished gown is a wonder on its own.

When Rose Byrne stepped out in the number at the X-Men Apocalypse screening in New York, she was showing off the original design that debuted on the runway. It was a slight variation of the one Olivia wore just a few days earlier, her commercial version featuring a sheer skirt and extra chiffon at the sleeves.

While Rose finished her outfit with a matching star pendant necklace by Atelier Swarovski and simple Jimmy Choo pumps, it was the princess-like details on her sparkling dress that confirms its staying power on the red carpet. In fact, we expect it might even go viral, just like the playful Gucci gown Dakota Johnson wore on Jimmy Fallon, before it hit magazine covers and editorials everywhere.

Read on to see how Rose and Olivia rocked the silhouette, then see it on the model when it hit the catwalk in March, complete with a furry bolero, edgy moto boots, and layered chains.
