We weren’t going to include two eyeliners in this lineup, but the multiple raves (19 and counting!) over longtime cult classic Stila practically forced the issue. In short: this is their number 1 selling waterproof liquid eyeliner for a reason. “I’ve tried every eyeliner that exists and nothing works better than Stila’s felt tip Stay All Day Waterproof liner,” says Michal Kurtis, who admits to wearing a cat-eye since she was a pre-teen. “I’m pretty much on a replenishment program, I should invest in it!” But we think Helen Rosner may have put it best. “I can’t even count how many of these I’ve bought over the years. 50? 100? It’s the best goddamn eyeliner in the universe.”
