The most flattering to my complexion will be purple, bottle green or navy, though I have read in reviews that navy is duller in real life. Neither of the first two options are super versatile in terms of pairing with the bottoms, but I do expect to wear with jeans or black or navy trousers. But I love green and purple.
However, I have just watched Audrey Coyne style a white one in many ways and have been totally seduced by versatility. The concern with white is that it will be see through and may be a bit secretarial without jeans?

So, which one?
