Taylor Swift has a close-knit group of famous gal pals (which includes Lorde and Selena Gomez), but her latest BFF has taken her style game to the next level. Since meeting at the Victoria's Secret Fashion Show last year, T-Swift and mega-model Karlie Kloss are inseparable. Not only did they give us serious vaca-envy on their epic road trip, but they were snapped yesterday in NYC looking cool, coordinated and classic. Highlights of their smart daywear? Taylor's gingham shirt dress and Karlie's spring-perfect slouchy trench. Nice work, ladies — keep doin' what you're doin'. 

See how to do a girls' trip, T-Swift style.
