She’s a style icon for a reason. Who else could make a button-down shirt look utterly playful and chic? Of course, it didn’t hurt that Audrey’s waist was so tiny that she could tie her shirt into a knot at the back. But that’s neither here nor there, dears. When we spotted this photo of Ms. Hepburn, taken on the set of Sabrina on Long Island in 1954, we knew we had to get the look. Starting at the top, of course, with a timeless gingham shirt. And the timing couldn’t be better, as GAP is offering a 20% off code on all regular-priced women’s styles through May 7.
