The Puerto Rico police uniforms have changed in style and color over the years. The PRPD uniform of the 1930s was a long-sleeve, navy blue button shirt, with a gun belt about the waist and support crossing the chest. Navy blue pants had a black line on the side of the legs from the waist down. In the 1960s, the only change to the uniform was the gun belt. The strap for the gun was only at the waist. In that same year, the patch was the Great Seal of Puerto Rico under the name "Policia de Puerto Rico" (Police of Puerto Rico).
