1. Katy's foundation coverage looks quite full in the video, and a polished look was achieved using highlighter rather than a dewy base. You will need medium-coverage foundation (Bourjois Healthy Mix in #52) and a soft beige/champagne highlighter (TheBalm "The Luminizer").
2. This is a very classic contoured eye, shaded in the outer V and along the socket line. There are 2 colors needed. A pearlescent peach-based gold and a basic grey/black. (I used the 88 Shimmer palette.)
3. Using the black shade, first pack into the outer corner of lids, then in an arc along the socket, stopping before reaching the center. Then trace all along the top lash line, and 2/3 of bottom lash line. It will look dramatic now, but you're going to blending it out soon.
