I sort of agree with Iris, and think she might be saying what Diana Vreeland is saying - but in a nicer way. And that is, to have style, you have to know who you are. If you don't know who you are, then you and your style will probably be all over the place, neither here nor there.
But I say sort of, because I don't quite get what it means to know who you are. Lol!
Like how many people really understand why they do things when they do them? I mean, you know how everyone says, 'Omg, I'm turning into my parents!' Why are we always surprised?
