Long before my time of course, but Pete still wears Mecca sandals all the time - the Jesus type with buckles (not the jellies that some wore) - he's got a pic of everyone (Judith, Len, Ian, Les etc) arseing around with Bernie Golding in grey bondage trousers, he tells me the wonderful Judy Moss used to go in a ra-ra skirt with full petticoats, he also remembers clear plastic anoraks (and someone even turning up with the pockets full of water with goldfish in - though this may have been at the Warehouse (Leeds and full disco mode) and somewhere we have a shot of Les in his notorious hard hat and tool belt a la the Village People.
Wedges (with or without tramlines - sometimes dyed rainbow strips) are surely later - I remember them in the early 80s along with whistles and cow bells amongst the Oxford/Swindon/Gloucester crew.
