Reese Witherspoon [1] has attended many an award show over the years, donning countless glam ensembles, yet one outfit in particular stands out in her mind: her 2006 Oscars dress. The beaded vintage Christian Dior gown is an iconic red carpet look, so it's no surprise that the Little Fires Everywhere actress [2] still thinks about it often. The champagne-coloured dress with gorgeous embellishments was certainly fitting for the Oscar winner, who took home an Academy Award that year for best actress in Walk the Line.

In response to a Twitter thread [3] that started with Twitter user @sydurbanek [4] asking her followers, "What's an outfit you think about a lot?," Reese shared an adorable throwback photo of her wearing the striking dress. "I have fallen in love with so many costumes over the years and I keep one from every movie," she wrote. "But one special dress stands out! My Oscar dress in 2006: it was a 1957 Christian Dior bought at a vintage store in Paris. So dreamy! Sparkles✨" The beaded dress was dazzling on its own, but Reese took it to the next level with equally sparkly chandelier earrings and a chic updo. Ahead, read the actress and producer's tweet and get a closer look at one of her best red carpet looks to date.
