For thoughts and secrets: the TOPModel diary only opens when the correct four-digit code (which can be set and changed personally) is entered. Then Taylor Swift's top hit Anti-Hero plays (approx. 20 seconds). On the outside, the pale pink diary has a delicate pattern of flowers, stars and small cowboy accessories and a large double model motif. Inside, 80 finely lined and colourfully illustrated pages are waiting to be written on.
