There are different kinds of ombre lips, but this is the version that I like doing the best. It makes the lips look more plump and pouty. This post is a demonstration of how I do it and I just used the colors in my collection. Feel free to use any 2-3 lipsticks in your collection.
Dark colors aren't always everyday friendly, but I still like to wear them. Doing lip ombres like this allow me to wear dark colors, but they aren't as dramatic.
For the lightest color, I made sure to use a kind of glossy color because the shine helps with the illusion of fuller lips. Lip gloss could even be added to the very center of the lips to draw in even more light.
