Jessica Chastain in YSL
FameFlynet

As the face of Saint Laurent’s new Manifesto fragrance, Jessica Chastain earned herself a front-row seat to the label’s fashion show in Paris this week. What to wear for such an important event? The actress took a page out of YSL history, thanks to a little help from Decades, the Los Angeles luxury vintage boutique, and her stylist, Elizabeth Stewart. “We just ransacked our archives of original Yves Saint Laurents to find the quintessential Parisian look for the show,” Cameron Silver, co-owner and founder of Decades, told InStyle.com. Their pick: A black and white polka-dot Rive Gauche halter dress from the ‘80s. “It created a very modern yet timeless look,” he continued. “Elizabeth did the final fitting right before the show in Paris, since Jessica flew in from New York City where she is in rehearsals for The Heiress. I think my persistent texting may have been slightly distracting to the two of them, but I wanted to make sure we had Jess covered!” And covered she was—her look earned a coveted spot in InStyle’s Look of the Day section.
