Raspberry Diversion ????? HELP PLEASE

Hi all
Could any of you please help me in my search for a "Rasperry diversion"
T–Shirt as I am a collecter/researcher of British fashion clothing,
particularly T–Shirts.
I Heard of this brand from an independent designer shop in yorkshire
who were keen to stock this brand for the coming summer season but
could not locate the source (strange but true).
Do you have a T–shirt (if you do your very honoured) or better a
location/contact of any official distributers or even the designers
themselves whom i cannot track down.
thanks in advance
