The Class I uniform was the "fore and aft rig" which in previous Uniform Instructions was the dress reserved for Chief Petty Officers, now included all Ratings Not Dressed As Seamen. Class I blue uniforms were made of fine wool serge, and were comparable in quality to the jackets worn by Officers. The major difference between this and an Officer's jacket are the 6 gilt buttons, compared to the Officer's 8.

The white Class I uniform jacket was also similar to that worn by officers. Both were made of cotton drill material, but the Petty Officer's jacket had 4 buttons whereas the Officer's jacket had 5.
