Fox joined Mitzi Lorenz from Otto Lucas, then went to Langée in Brook Street, Mayfair. When he died in December 2013, numerous sources cited the pink hat with 25 fabric bells that the Queen wore to mark her
Silver Jubilee at a thanksgiving service at
St Paul's Cathedral as Fox's most famous design for the Queen. But it was confirmed by the
Royal Collection Trust in August 2016 to be the work of
Simone Mirman. In films, Fox designed the white "crash helmets" worn in
2001: A Space Odyssey (1969) and hats for
The Great Muppet Caper (1981) and
Evil Under the Sun (1982). ==Honours and assessment==
