From A Sailor's Look Back:

"Liberty was the highlight of a sailor's life after being out to sea for three to six months. Most sailors had two dress uniforms: one was for inspection GI (government-issued) uniform, another was for liberty. This uniform was tailor made out of the best cloth that could be bought. The tailors on Sand Street in Brooklyn, N.Y. made a fortune making uniforms for sailors."
