To do this shimmery gray eye makeup start by making an outline with a black eyeliner and a thin brush. Apply black eyeshadow at the corner of your eyes inside the outline drawn. Then apply a bit of white eyeshadow to the inner corner of your eyes followed by shimmery gray eyeshadow. Finish the look with a black eyeliner and mascara.
Your party makeup is ready to rock.
