Anne Hathaway – who has cemented herself as a luxury fashion icon – recently stepped out in a custom look from an affordable American brand, much to the excitement of fans.

On May 20, the Idea of You star attended an event for Bulgari in Rome, Italy, wearing a white ʙuттon-up shirt dress with a built-in corset, custom made by Gap Inc’s newest creative director, Zac Posen. According to a press release, the dress was designed from the same cotton material as Gap’s signature white shirt.

Referencing the American label’s classic cotton ʙuттon-down, the dress featured a wide collar which Hathaway had draped off one of her shoulders. The ensemble was only ʙuттoned twice in the midsection, revealing a matching sheer corset also designed by Posen. Hathaway opted to wear a pair of pleated shorts under the shirt dress for a thigh-high slit effect, and styled the look with white pointed-toe heels.

For accessories, Hathaway wore a diamond Bulgari necklace with a blue sapphire center stone, a silver snake wrap bracelet, coordinating earrings, and a diamond and sapphire ring.

In a post shared to Instagram, her stylist Erin Walsh explained that the dress was inspired by the wardrobe in Audrey Hepburn’s 1953 film, Roman Holiday. “An unforgettable night in Roma with @annehathaway for the @bvlgari Aeterna High Jewelry show,” Walsh wrote in the caption. “We wanted to capture a modern take on Roman Holiday. Don’t you guys love how fresh and fabulous and glowing Annie looks???? Thank you Zac for a fabulous new era at Gap. And those jewels tho.”

While Hathaway’s dress was custom made by Posen, Gap shared in the press release that the brand “will be offering a version on Gap.com” in the near future, per Fashionista.

On X, formerly Twitter, fans were elated that Hathaway decided to wear an item from the affordable retailer, rather than a high-fashion look.
