By now it should be clear that we're loving everything and anything metallic for the festive season. If you don't want to be bothered with all the smoky eye blending or winged shadow shaping, then take a page from Dua Lipa's book and apply black liner, coat your lashes with lots of mascara (maybe some false lashes if that's your thing), then simply add a touch of twinkly silver shadow or eyeliner along the inner rims of your eyes for a flash of shine that's as understated as it is glamorous.
