I am assuming that Margot may be making an appearance at the Oscars tomorrow, especially as she as attended quite a few Oscar weekend events. But then again I could be completely wrong, and it’s just a role for her Chanel ambassadorship.
Margot’s full look, including top, pants, bag and presumably jewellery is from Chanel. I haven’t found them online yet, so they could be custom or not yet released.
The post shall be updated as more information appears!
