There are a few uniforms.
Navy wear Black with white pants, although earlier on they were also wearing blue.
GF uses brown, but higher rank GF officers are also seen wearing blue, so I'd say that the Browns are Class Cs while Blues are Class As/Dress Uniform.
Enforcers use black.
AF uses white jacket with blue pants/miniskirt.
...come to think of it, Roy Mustang would be happy in the TSAB. Regulation miniskirts.
