Rules are made to be broken. Who said curvy women should only stick to black, or that tall girls shouldn't wear heels? Experiment and wear what you feel -- what's important is that you know exactly what looks best on you and what makes you feel good. Fashion has always been about having fun anyway, right?
People have many layers. If you love yourself, a good metaphor for you is to think of people like an onion--rings upon rings of flavor. People also have a lot going on beneath the surface--think of an iceberg. Only the very tip is above the water for us to see. Some people might seem boring on the surface, but their story lurks just beneath the water.
