There are beauty secret weapons, and then there is Stila's Stay All Day Waterproof Eyeliner.
Ever since it first debuted many seasons ago, the felt-tipped black pen has become a staple backstage at fashion shows and everyday life alike, thanks to a practically permament formula that lasts through essentially anything.
Thunderstorms, pool parties, sweaty concerts, showers...your cat eye will survive.
To celebrate the fact that Stila's finally rolled out a full colorwheel of hues, we had to put the new set of inks through the ulitmate tests. See how they did in the gallery!
