>> Swap out your statement necklace with a pin, à la Alexa Chung at the launch of 30 Days of Fashion and Beauty in Sydney earlier today. Strategically placed right in the center of her buttoned-to-the-top collar, Chung's bow-shaped brooch is a cute alternative to this season's collar necklaces and chokers. Like the look but want to wear something a little less twee? Try the same placement with any style of brooch — we think something hard-lined and geometrical would look equally cool. For a few ideas, shop the look below.
