Reese Witherspoon 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 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 that started with Twitter user @sydurbanek 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.
