The party season has officially arrived! Celebs and fashionistas are stepping out in their best glam and black and white looks. Here are our favourite looks of the week:

Poppy Delevingne goes for a very sparkly outfit – pairing sheer and glitter perfectly.

Constance Jablonski wore black and white at Derek Blasberg’s recent party in New York.

Jessica Alba looks lovely in this power pink peplum dress.

Edie Campbell also donned black and white in stripes to the same event.

Carey Mulligan looks pretty as a peach in this black and sheer look.
