I'm a big fan of Bobbi Brown's great Long Wear Gel Eyeliner ($21) for waterlining and intense pigment, but Bobbi doesn't make bright teal, which is one of my favorite shades to wear, so I turned to HIP Color Rich Cream Eyeliner ($12). I like it because it sticks nicely on the rims of my eyes, and therefore I don't have any trouble with bright blue smudges. If you're a fan of waterlining, I highly recommend this one. Just make sure you apply your eyeliner before your under eye concealer, so that you can clean up any inadvertent slip-ups. Bonus: Something about the blue-green shade will make you feel extra runway-ready. That, and it's totally '80s cool, without the dated, neon quality.
