• Sidearm: .38/.357 revolver in leather holster (officers only; towers had rifles)
• Headgear: Eight-point cap (winter), straw hat (summer) — later baseball style
• Insignia: Rank chevrons (corporal, sergeant, lieutenant), service stripes

Special Context

• Uniforms issued, not purchased — government property
• Laundry: Inmate-operated (industrial) — twice weekly exchange
• Contraband control: Uniform design minimized hiding places
• Psychological: Uniformity reinforced institutional identity, depersonalization

Alcatraz's clothing regime: control, visibility, hierarchy—woven into every seam.
