Who doesn't loves vintage, am I right? f(x)'s Krystal looks effortlessly flawless as she takes it back to the past as the cover girl for the October issue of 'Nylon'!

Sporting Keds with 'Boyfriend' jeans and high-waisted skirts, Krystal proves that she can easily pull off any look, including '70s fashion (which isn't the easiest fashion decade to pull off). And to top it all off, she finishes each look with her signature nonchalant gaze. She is one cool cat, indeed.
