Eyeliner from Sephora?

I need new eyeliner and I was going to go to Sephora but I don't know what to get there's so many choices. I want an eyeliner that LASTS ALL DAY and doesn't smudge or come off. I also want it to look natural, I don't like when you can see a harsh line of eyeliner on the top lid. Maybe I should get eyeliner that is like a brush and packed eyeshadow? I want it to look more natural and stay on all day while still making my eyes pop!
