33rd Annual Gotham Awards

Margot is wearing custom Prada (as confirmed by @checkthetag ) with her look tonight is based on the 1964-1965 Black Magic Ensemble Barbie!

On the red carpet, she revealed that this look was supposed to have been worn during the premiere in Tokyo which obviously didn’t happen due to the writers strike.

I do believe she is also wearing her custom Manolo Blahnik’s.
