Going with a nude makeup look also doesn't mean going without makeup. Try a taupe colored eye shadow and use a medium brown eye pencil to gently dot between your eyelashes to give the illusion of a thicker lash line. You can also still use an eyebrow pencil to fill in your brows so they still look full and defined. Don't skip the mascara either and choose a flesh-toned nude lip liner followed by a peachy-nude lip gloss to complete your look.
I know I skipped over talking about the foundation part but you really shouldn't when actually trying out this look. Still use a concealer and a foundation to cover up imperfections. I still use a powder foundation over the top as well because I tend to get greasy spots on my face as the day progresses.
