While she continued to dance and sing through each of her eras (including the latest: The Tortured Poets Department), her signature red lip was performing, too. Fantastically well, actually — it never seemed to smudge or fade throughout the hours-long routine.Swift has been wearing a ruby red lip… well, since her Red era. Vogue got the first scoop that her signature lip for the “Bejeweled” music video came from Pat McGrath’s incredible make-up collection. Swift wore her LiquiLUST Legendary Wear Matte Lipstick in Elson 4. It’s believed that it’s her signature shade – seeing her through everything from Super Bowl smooches to rainy performances.

At the end of the damp show, Swift thanked her fans for dancing in the rain with her. And if that’s not a sign of an excellent performer, I don’t know what is.
