Here are some that I love and think you will too! (I'm a total eyeliner junkie )
Lancome ARTLINER - Precision Point EyeLiner ... I like it in Noir, just as regular black, but Smoke is really pretty and softer than black, without being brown.
Urban Decay 24/7 Waterproof Liquid Eyeliner is great at staying on all day... it doesn't budge until I wash it off!! It comes in lots of shades, my favorite being Perversion for everyday and Siren and Woodstock for wild looks.
Tarte MultiplEYE™ Lash Enhancing Liquid Liner is awesome because it comes in a pen which makes it SO easy to use and, my favorite part, it has lash-nourishing ingredients in it (it does touch the base of your lashes so it only makes sense)!
Last, but not least, SEPHORA COLLECTION Doe Eyed Felt Eyeliner is great because it's inexpenisve, has a convienient pen format, and looks great. I love the color Brown to bring out blue eyes.
Hope this helped!!
