A version of the custom white Gap shirt dress that Oscar-winning actress Anne Hathaway recently stepped out in was released for limited pre-order on May 28 — and shoppers snatched the piece up quickly.

The Idea of You actress, 41, was photographed wearing the floor-length dress, designed by Gap’s new creative director Zac Posen, at an event for jewelry brand Bulgari in Rome earlier this month.

Hathaway’s stylist Erin Walsh paired the gown with several Bulgari jewelry pieces and white matching heels for the event.

The floor-length dress is off-the-shoulder and includes buttons similar to Gap’s iconic white dress shirts, which was styled to reveal a matching semi-sheer corset underneath. Hathaway’s white corset is not part of the dress available for retail.

According to a press release from Gap, the Poplin White Shirtdress is a “reinvented take on Gap’s iconic white shirt” and “elevates the classic piece with a modern silhouette as a canvas for original style.”

Posen also shared in a press release that it was “an exciting opportunity to reimagine Gap’s classic white shirt” for Hathaway. He was inspired by the “elegance of Audrey Hepburn in Roman Holiday” and incorporated “elements like the shirt’s collar and placket” and “feminine touches with darting at the waist” in order to create a more modern approach to the timeless style.

The Poplin White Shirtdress is made from 100% organic cotton and was available in sizes 00 and size 16. The dress was on pre-sale Tuesday, but sold out in under three hours after being listed online. It will ship to customers in July.

Along with the Poplin White Shirtdress, Gap will also be launching its white summer collection on May 29, which will feature white tees, shirts, jeans, chinos and dresses to serve as a “blank canvas for creativity and original style.”
