When Austrian born stylist (Emma Watson is among her clientele) announced her engagement to her financier boyfriend last year there were articles breathlessly wondering whether Karl Lagerfeld might design her wedding dress. I mean, for that question to even be asked, you might allow yourself to feel quite smug in that you are a definite Fashion Person. An official friend of Chanel and perennial front row/street style regular, Sieber is unafraid of high fashion. She's experimental and edgy but never strays too far from forward thinking polish. So she might wear a showstopping jumpsuit or Chanel frock but the colours will be kept simple. The result is that she leads the pack but very rarely stumbles.
