My definite #1 has to be Jennifer Lawrence in Christian Dior in Haute Couture:
There were loads and loads fabulous dresses on the red carpet tonight, I managed to pick a few I liked most, so there it goes:

^ From left: Annabelle Wallis in Dolce & Gabbana, Gemma Arterton in Celia Kritharioti Couture and Lily James.
