Journalists who received it were shocked to read the collection's new colours for autumn/winter included the menacingly titled Anthrax.
A subsequent email duly arrived, apologising for the 'unfortunate error' and assuring journalists: 'It should of course have read "Anthracite". Apologies and please find attached an updated version of the release.'
A spokeswoman jokes when we call: 'Fashion is all about innovation, so we thought would make up a new name.'
Olsen's collection, she later adds - admirably attempting to capitalise on our call - will not fail to be 'infectious'. Gulp.
