Acne's Pre-Fall 2012 collection is all about proportions. The Stockholm collective has created a mix of cropped tops, wide belts, boxy jackets, fitted trousers and micro-minis to pair with clunky, transparent rain boots. It's a perfect collection to weather all seasons. For a more girl-about-downtown look, pair these separates with their chain belt -- which is less Chanel and more bike messenger chic.
