Taylor Swift is no stranger to serving looks on and off the stage. Her bold red lip is one of her signature looks, and we discovered she's used this affordable $7 formula. Swift has used many red lipsticks through the years, and one of her picks is CoverGirl's Exhibitionist Lipstick in shade 305. It's a classic red hue that's not too rich and not too sheer. Aside from its stunning color payoff, it includes shea butter and avocado oil for a picture-perfect pout.
