I have been wearing eyeliner since I was about 15. I was inspired by a woman I worked with who would line her eyes perfectly with a nice crisp line, similar to how Adele does hers. I'm pretty sure she used an expensive liner but being 15 I headed to Longs (local drugstore/pharmacy) and bought my first liquid eyeliner.
I used this liner for most high school and college and I can't recall having too many complaints. I do remember feeling like my lines weren't black enough. I used the blackest black, but the lines tended to look dull and my cat-eye tails would always smear off. I was on a budget and this was good for budget.
After college another coworker introduced me to my next love affair liner. Learning to apply it with a brush took some time, but after a few days I was in love. I would recommend getting a longer brush, it makes application a lot easier but it's nice that they give you one for travel purposes. I wore this creme liner for years but eventually I started noticing that by midday my lines weren't as crisp. Apparently I have sweaty eyelids or something because my cat-eye tails were smearing/disappearing.
I decided to try another drug store creme liner...why not right? Wrong. I will say that this was the second time I tried this gel liner. I couldn't remember if I had tried the waterproof version the first time, so I figured I'd give it a whirl. This one was not great at all. I swear I would have barely anything on by the end of the day. And I'm sorry, I think $10 for drugstore liner is a rip off, especially if I could pay $6 more for Clinique. I like Maybelline but this liner is not good.

After that disaster I went to Sephora for some new liner recommendations. I had super high hopes because the girls in there have killer eye liner. First recommendation was Tarte Claypot Waterproof Eyeliner. I'd heard of this eyeliner before so I was excited to have a "professional" recommendation. I scooped it up and went home to try it out. It was waterproof, it was from Sephora, good recommendations, it had to be good. Not so much. Again, by the end of the day this stuff wasn't crisp and my little tails were either fading or non existent. I was shocked, for being waterproof I thought it would be better. Again, maybe I just have sweaty eyelids or something.

Bridesmaid to the rescue! I was at my girlfriends house for dinner one night and she was raving about her Stila eyeliner and that it stayed on all day and she loved it. I took myself back to Sephora and exchanged the above product for this liner. Now I was back to a more liquid application, with a new application style. This thing looks like a grinch finger and at first is a little intimidating, I definitely had to pull out the q-tips the first couple of days. After wearing it for 2 weeks, I love it. I feel like my lines are super crisp an stay on all day. It is waterproof, but it comes off so easily with my makeup wipes, which I love.
If you are looking for a liner, here are my top 3 recommendations starting with the best.
#1 Stila
#2 Clinique
#3 Tarte
I would love to find a drugstore version so once this runs out, I'll be on the hunt and report back, but for now I'm super happy to have found a fantastic liner from Stila.
