Relive Sydney Sweeney’s Dramatic Fashion Evolution Through the Years

Sydney Sweeney is no stranger to the red carpet. From sexy sheer dresses to waist-mincing designs, the Euphoria actress has no shortage of fabulous red carpet moments. One of the star's most buzzed-about red carpet fashion moments was from the 2021 People's Choice Awards, where she exuded Old Hollywood glamour. Sweeney donned a black velvet Saint Laurent mini dress adorned with a large satin bow detail at the base of its plunging neckline. Sweeney again made headlines in April 2025 for wearing a bridal look days after an insider told Us Weekly she and Jonathan Davino had called off their wedding. As she promoted The Housemaid at CinemaCon in Las Vegas, she wowed in a figure-hugging ensemble from Wiederhoeft’s bridal collection.
