What I love about metallics is that they make the most normal item, a jean jacket for instance, instantly icy cool. Or a boot: black leather is just fine and dandy but make it metallic and now it’s a whole other thing. This season, metallics look like mercury: shape shifting and absolutely glimmery. Think tin foil more than sequins. And they come in fun, futuristic, ultra shiny colors, such as lime green, grape purple and steely blue.
