Let's discuss one of the oldest fashion rules in the book: don't wear black and navy together, or you shall be shunned from the style community and left in the middle of Lincoln Center to be publicly humiliated (we made that last part up, but you see where we're going here). The oft-ridiculed pairing was pulled off on Spring runways from Lanvin, Victoria Beckham, Stella McCartney, and more and has been road-tested by style mavens like Alexa Chung and Chloë Moretz. The look is absurdly easy to achieve — it can be as simple as pairing a navy tank with black jeans, tucking a black tee into a navy pencil skirt, or just wearing black tights with your favorite navy dress. No matter how you try it, the trick is to keep your navy truly navy — if it's dangerously close to being black, it'll just look like you got dressed in the dark (unless, of course, you really did get dressed in the dark, in which case we can't help you).
