From a London Film Festival to Paris Fashion Week and TV show appearances, the style memo this week was easy glamour.

The Crown’s Claire Foy was breathtaking in a floor-length Gucci gown at the BFI London Film Festival, while Katy Perry dazzled in a sequin Attico cocktail dress that made the case for having fun with fashion when she arrived at the Good Morning America show.

As we’ve seen with Paris Fashion Week’s street style this week, the capital of love and nonchalant fashion was inundated with fashion celebrities.

From Julianne Moore decked out in Louis Vuitton to the Fanning sisters in matching Miu Miu, there was plenty of inspiration to see.
