I purchased this in Pale Pink along with her lipstick in Shell and they are the perfect compliments to each other. I have never found and loved a liner like this. I typically ditch the liner as I have never loved the application or formula and never really noticed a difference. Bobbi's products are different! I follow their recommended technique of applying the liner after the lipstick to set it and give a subtler and softer liner look. Flawless. You won't want to use any other liners in the future. Unlike other liners like MAC or other high end brands, these don't feel like a colored pencil being dragged across your lips--no tugging or dryness here.
My skin tone is light brown and SLOPES is the perfect color for my dark hair/eyes. Can place reds, pinks, brown lipstick and it seems suited as a base color for all. Pencil is soft/firm at the same time. Sharpens well (doesn't break), and glides on without having a pencil effect. Last pretty much all day.
