It's a toughie! Pink eye makeup can either look really cool or really terrible.

But despite the risk of making models look like they're sick, several designers at New York Fashion Week have sent girls down the runway sporting pink eye makeup.

A few tips from the pros on making the look work: Anchor the color with brown eyeliner, like makeup artist Polly Osmond did at Tuleh. Have a heavy hand with black mascara, as seen by makeup artist Nadine Luke at Alice + Olivia.

Or just have fun with it like makeup artist James Kaliardos did at Ruffian!
