I think that the most important thing I've learned from this thread, or rather from the models in it, is the importance of minimalism.
Clean lines, clean colors (dark or light) and no crowding the outfit with trinkits and a jillion bangles and big belts and big earrings etc etc. Even the scarfs and shawls flow with the rest of the outfit instead of standing alone.
It's seriously changed my style and made me shop differently.
