Figure 1.--Many of these French choristers wear caps unlike those worn by any other French choir that HBC has noted. We think that perhaps they were gifts after appearing at some kind of East German Young Pioneetr event.

Choir boys do not commonly wear caps. Some of the German and other choirs wearing sailor suits wore sailor caps. (I do not know of any who have worn sailor hats.) The British choirs located in cathedral schools often wore peaked caps, but this was more their school uniform than a choir costume. Some choirs may have been photographed in caps given to them on their various trips.
