Tying a sweater across the chest is quickly becoming mainstream — we're even seeing the move on the runway at ALEXACHUNG and Victoria Beckham. Draping my POPSUGAR at Kohl's red stripes ($37, originally $50) over this asymmetrical Amur denim dress ($348) wasn't just about the visual effect, it's a functional way to carry another layering piece in the Fall in case you get cold. In an effort to stay hands-free, I swung my Karen Millen belt bag ($163) around the shoulder and kept it simple in block heel sandals.
