Figure 1.--Here we see two German children with their mother. The portrait is undated, but looks to have been taken in the 1910s. Both children wear white three-quarter socks.

Three-quarter socks were commonly worn by German boys. Three-quarter socks were socks higher than ankle soks, but lower than knee sicks. Thi covers a range of specific lengths, complicated by the fact tht children sometimes pulled them up or let them fall dowm. Three ey were a srandard hosiery type for younger boys and girls throughout Europe and North America. They do not seem to have been as commonly worn as in France. I think that was primarily because long stockings were much more common in Germany than in France. German children in the early 20th century mostly wore eith three-quarter or long stockings. This was in large measure a seasonal choice. I'm not sure when they were first worn, but they were very common by the turn-of-the 20th century. They were worn in the early 20th century, but after World War I (1914-18) in the 1920s they ere rarely seen.
