Theres no wrong way to wear black eye liner. For drama, rim your lash line with Nars Black Mood Velvet Eyeliner, then add a dark shadow over it (I recommend Giorgio Armani in Eyes to Kill or Nars Dual Intensity Shadow in Sycorax. ) I apply the the dark shadow over my lash line with my eyeshadow brush (can be applied wet for even more drama) I then take my NARS fluffy blending brush and blend the shadow and pencil together. For less intensity apply the shadow stick from YSL your lower lids only. Curl your lashes and finish the look with two coats of mascara.
