The global instantaneous appearance of a fashion item with little or no value other than cost and the purposes of parting people with more money than sense from their cash. Not to be confused with a Cashmeaner
which is a fashion item resembling one bought at Hermes but actually bought outside the railway station or Fashmeaner
which is style originating from the thrift shop. Or a Fashwiener
which typically refers to a male person and who has more money than fashion sense and follows the "mutton dressed as lamb" code of clothes buying. Definitely not to be confused with a pash
which has nothing to do with clothing at all.
A group of ladies sat overheating in a cafe wrestling with their new Cashminas for which there was no cloakroom, no handbag space and no use other than talk about how necessary and expensive they were.
