The hottest hues currently trending? Copper and rose gold. These two metallics were big news in interior design for 2015, and are following suit in fashion for the new year. Whether a subtle embellishment on a classic (see adidas Originals Superstar 80s Rose Gold editions that I'm currently obsessed with), a little touch of stationary, or a pair of precious metal shoes, it's the need-to-know update that'll send your style credentials soaring. Test the waters with a copper chrome-dipped manicure.
