There's a sprinkling of exclusive events taking place throughout the week too - from the Vogue Foundation dinner (which had Emily Ratajkowski and Cara Delevingne in attendance) to the glitzy Chanel fragrance launch at Palais de Tokyo.
Of course all eyes are going to be on the outfits and we've spotted some of our favorite celebrities in some fantastic ones so far. Priyanka Chopra chose a white thigh-skimming number for Giorgio Armani show and Jennifer Lawrence dazzled at Dior in an exquisitely embellished gown.
