Sienna Miller arriving at the 2015 Academy Awards on Sunday, February 22, 2015 at the Dolby Theatre in Hollywood, California.
Sienna starred in two Oscar nominated films this year, and was on hand to present. For her return to the Oscar red carpet, Sienna is wearing an Oscar de la Renta Fall 2015 Collection gown - that debuted last week during New York Fashion Week.
The look from the Oscar de la Renta Fall 2015 Collection presentation. I prefer the catwalk version, the lining (or lack of it) makes the dress look much lighter.
