Fashion month has reached its final leg in Paris. Olivier Rousteing’s bash at Lapérouse in the City of Light drew the likes of Kris and Kendall Jenner, Jared Leto and a bevy of models. Earlier this week in Milan, Riccardo Tisci booked Nicki Minaj for his Givenchy after party. Stateside, the New York City Ballet threw its annual fall gala and “The Martian” screened at the New York Film Festival. Here, the best party photos of the week.
