Here is a clothing LoRA of the uniform worn by the Eight Gentle Judges in Megaman Zero.

Recommended Weights are: 1.0-1.5 (I found it to be more accurate towards 1.5)

If I had to give an 'In-Universe' Explanation for this, well:

All judges in Neo Arcadia wear this uniform

Unlike the Eight Gentle Judges who mainly deal with Mavericks, these ones deal with 'lesser' crimes that are committed either by a Human or a Reploid

These judges can either be human or reploid
