I used a NYX lipliner in Peekaboo Neutral. It’s exactly what it sounds like, a nude shade with a touch of peachy-pink. If you’re only concerned with definition, just line your lips. But I want staying power and bit more color, so I went ahead and filled them in. Top it all off with a sheer peachy nude gloss. Mine is Revlon Colorburst Lip Gloss in Peony.
