Stila Stay All Day Liquid Liner in Cobalt, $20.

“When it comes to shadow, I would skip and do a fun waterproof liner,” says Blushington Makeup and Beauty Lounge head makeup artist Jessica Scantlin (she’s dolled up Chloe Sevigny, Ali Fedotowski and Karmin). She loves this cobalt liner because it sets in seconds and doesn’t budge all day (and night) long.
