Acne Studios - These grey-beige Perrie trousers feature in Acne Studios' AW19 runway show, for which creative director Jonny Johansson offers a retro-futuristic take on work clothes. They're made from wool-blend twill with a high-rise, paperbag waist supported by sharp pleats, which then run along the straight legs as neatly pressed creases. Use the belt loops to complement it with a contrasting belt.
