The original Cato range was announced to the press with the range of coloured stripes, but there is now evidence of Cato with gold lines and plain Cato with floral decoration. The former appears to be a production line, but I'm unsure about the latter as the floral motifs are hand-painted, not transfer. Photos of these will appear in Additions.
It is possible the clear ones were remaining stock, or they simply sold the range without decoration - perhaps to a third-party?
