The actress attended the Louis Vuitton Cruise 2016 Resort Collection in Palm Springs, California on Wednesday, where she stunned wearing a patterned cocktail dress and black booties.
The "My Week with Marilyn" actress also debuted her even lighter, platinum blonde locks, which fell right above her shoulders. Williams finished her look with natural makeup and styled her short blonde tresses in loose waves.
While we've rarely seen the "Dawson's Creek" alum at public events recently, she definitely stole the spotlight sitting front row at the Louis Vuitton fashion show.
It does help that the 34-year-old is close with the French fashion house -- the "Blue Valentine" actress has starred in three of the brand's campaigns!
Michelle definitely looked like she was enjoying herself, too. Williams was spotted chatting with stars like Selena Gomez, Miranda Kerr and Catherine Deneuve at the high-profile event.
