How to decorate big lips?
Too big lips always extend to both sides and always look awkward. For this lip decoration, concealer can be applied to the lips including the lip surface and fixed with honey powder. When drawing lips, the outline should be drawn inward, so that the original lips can converge.

For the ideal lip shape with clear outline, raised lip peak and round lip shape, there is no need to add more decoration. Just draw a thin and solid lip line according to the original lip shape and apply lipstick. But it should be based on the fact that when the lips are open, the lip angle can't show the real skin of the lips.
