About 10 years ago I discovered MAC Fluidline after doing CRAZY amounts of research on eyeliners. After trying about 30+ varieties, MAC Fluidline is definitely my HG eyeliner that I still use religiously to this day.
I love this eyeliner, but it took me a couple time to perfect putting it on. I purchased the MAC 210 Precise Eye Liner Brush to apply it. The eyeliner stays put and does not smudge or wear off (I used an eyeshadow base also). Great for everyday and would be perfect for an evening out or weddings!
