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