I don't wear make-up on a daily basis but I wanted a good water resistant long lasting eyeliner. I decided to get something from mac since I've been seeing mac product in my best friends beauty bag for a while. I was blown away by fluidline which I bought in blacktrack. It's long lasting, water resistant, sweat resistant and smudge proof. I actually took a shower with it on before going to bed after a night out like I do with most eyeliners thinking it would come off but after my shower I had to use my trusty clinique make-up remover to get it off. It dries quickly too so you don't have to wait...
