It is true that many women want to have sexy, fuller lips. Therefore, if you still want to apply lip liner in order to get plumper lips, make sure you always do this before applying the lipstick, and use a neutral one lip liner, or one that has the same tone, or even lighter than that of the lipstick you are applying. This way you will avoid a too big contrast that would only draw unwanted attention. Always apply your lip liner before applying your lipstick to give it great staying power, and never use a lip liner that is darker than your lipstick. For that ultimate supermodel look that will make guys fall to their knees, dab a touch of gloss in the center of your top lip. This will make your mouth look pouty and sexy.
