Whether you're looking for a subtle line or you're hoping to channel a 1950s movie star, you can NOT go wrong with Buxom Lashliner. My sister in law, Cameron, bought both the eyeliner and the brush for me last Christmas and I can't tell you how much I love the stuff. I'm telling you, just the act of putting it on makes you feel like you're getting ready for something special...even if it is just a 9 am meeting. I would highly recommend picking up the Buxom Lashliner Brush if you're going to get the eyeliner. I'm sure there are cheaper versions out there, but I have never missed a line with that brush. A little soap and water every now and then and it's good as new.
I assume the eyeliner lasts forever too. I don't use it every day but at least every other day and I've barely made a dent since Christmas 2010.
It's a bit of a guilty pleasure but SO worth it!
