Sienna Miller’s red carpet evolution often hinges on her ability to pair feminine silhouettes with bold, structural footwear.

At the 2020 Writers Guild Awards at the Edison Ballroom in New York City, she leaned into this signature aesthetic by styling a pastel yellow Rebecca Vallance midi dress with authentic Gucci platform sandals. The choice of a heavy platform grounded the delicate satin-jacquard fabric, a styling trick that remains a staple for the actress.

Rebecca Vallance launched her eponymous label in 2011, quickly becoming a favorite for celebrities like Maria Menounos and Halle Berry.

Miller’s specific dress has since become a reference point for chic, daytime formalwear, often appearing on luxury resale sites like Net-A-Porter and Farfetch.

The standout element, however, remains her Gucci sandals. These high-heel platforms are a versatile red-carpet favorite; notably, Yara Shahidi also wore the same style to the 2020 NAACP Image Awards. You can still find current iterations of the Double G platform at Farfetch.

Standing at approximately 5ft 5in (165.1 cm), Sienna Miller is relatively petite, making her red-carpet footwear choices more than just a fashion statement—they are a lesson in vertical proportions. By choosing a high-heel platform rather than a flat or a kitten heel, she avoids being overwhelmed by the midi-length hemline of her Rebecca Vallance dress.
