This is probably one of those old ECA (now known as CCA) at Cedar Girls School in 1968. Photo shown both my ‘godsisters’ dressed in the traditional Scottish Highland Kilt dress.
Please correct me if I’m wrong; they are probably performing those Scottish Highland dance. The one on the right with black top was dressed as Man while the other (white) was dressed as Woman. The Man will have a Sporran (pouch) with a long chain round the waist. Also see those long hose (socks) worn by them.
They were probably dancing the Gillie Chalium (sword dance). This is one of the very old ECA and I wonder if such ECA still exists in our school now?
