We love it when two of our favourite royals collide. And that's exactly what happened when Kate Middleton (aka Catherine, the Duchess of Cambridge) joined Crown Princess Mary of Denmark during a visit to the UNICEF Emergency Supply Centre yesterday in Copenhagen. Both Kate and Mary were catapulted from their "commoner" status to regal stylistas when they married Princes. That's not the only thing they have in common though — they also have impeccable style, not to mention great hair! But who won in the strand stakes yesterday? Are you a fan of Kate's signature bouncy blow-dry or do you think Mary's half-up, half-down style is a must?
