What uniforms did The Italian and German POW's wear in World War 2?

Most photos show Italian and German POW's wearing their uniforms. I'm sure many had to have new uniforms or clothes issued to them so they could work OR because they were captured in a desert uniform and needed warmer clothes. After Italy surrendered in Sept 1943, the Allies in Italy began to use some friendly Italians to haul supplies by mules or as translators. Many were issued British or American uniforms or clothes and some had a Green patch (about 4 inches & oval) with ITALY in white. This patch signified that they were friendly troops but were not soldiers who had security clearance.
