Thanks RM

There used to be a shop that sold vintage clothing on the High Street in Canterbury. I hain't been to Canterbury in over 3 years so don't know if it is still there.

Sometimes theatre groups will have a clearout of costumes (typically authentic fabrics and styling etc). But I don't know where they donate or sell the stuff. You might start a BS thread on Mudcat. You never know. Someone may have just what you are looking all lonely and forgotten packed in a box in the loft.
