Although many of my fellow contestants wore complementary costumes - and indeed, in Berlin in 2005, so did I:
...I have to report that it did not seem to impress the judges, and in spite of the elaborate costume, my comparatively miserable facial foliage efforts were not placed.
However, that isn't stopping me from appearing in a different guise this year, and another one that is essentially English. That seems to be one of the main criteria in choices of costume, to give a national flavour of the contestant's country.
