In recent years a range of books have come out on the Nationalist armies. Generally, however, they are spread over either time or place, so no army has really detailed information in English yet.
Armies of the Baltic Independence Wars 1918-1920, in the Osprey Elite series, gives some information on the uniforms of the Latvian, Lithuanian and Estonian armies. Its small size means each gets only a dozen pages though.
Nationalist Armies in the AST series on the Civil War covers the Baltics, Ukraine, Caucasus, Czechs and Poles in Russia, so the coverage of each is very limited. I have a translation if you can find a copy.
