Kylie Jenner Broke a Big Beauty Rule at the AMAs Last Night

The secret to getting Kylie's flirty, fluttery fringe was Eyeko Lash Wardrobe ($24). "They’re not individual [lashes] and they’re not in strips. They’re something in between, so you can layer them and create so many looks with them alone," said Rob. He also used Eyeko mascara in Black Magic ($24), a superdark, buildable formula. "The wand is curved so you can get into the lash line better," explained Rob. This trick is essential for pumping up a puny fringe — if you're wary of using falsies, getting extra mascara into the base of the lashes creates the illusion of volume.
