I just got these uniforms the other day at the flea market for cheap. Can anyone give me some info? Theres a black coat and slacks/belt, a white shirt and slacks/belt and a brown coat with three pairs of slacks.

You have a Service Dress Blue Lieutenant's Uniform (Line Officer has the star above the stripes), a Service Dress Khaki Uniform (needs shoulder boards to denote rank), and a Service Dress White uniform (also needs shoulder boards to denote rank). The Service Dress Blue and Service Dress White can be Full Dress when member wears large medals and sword.

Oh thanks! The service blues almost appear black..in fact I believe they are black.
