Prada - Prada's signature use of print shines through in this red and yellow silk dress - a key piece in the Pre-AW18 collection. It's tailored in Italy with a long necktie and gathered cropped sleeves, then shaped with off-centre gathers along the waist before falling into an asymmetric hem; a classic example of the label's subversive approach to feminine details. Anchor it with block heels for a casual high-summer dinner party.
