I've been meaning to redesign the guard uniforms for a while too! the unforms were always too plain and simple looking for my tastes, which is probably because i made the designs years ago with no design updates
so far the vibe im going for is for the uniform to be much more imposing, so it's now actually more modest, with a lot more padding and big sleeves that make the guards look even wider, another thing i wanted to go for is the sense that these uniforms were also made by the warden, and share a lot of design elements as the prison uniforms ^^
