The Faultless Pajama Company, originally E. Rosenfeld and Company and then the Rosenfeld & Steppacher Company, was a Baltimore-based garment manufacturer that began operation in 1881. The factory was located in downtown Baltimore, on the corner of South Paca and Lombard Streets, in what is now referred to as the Westside. It was one of the Baltimore garment industry's major employers. The company was best known at the time for its jingle "My Faultless Pajama Girl". This piece, a fox-trot, was composed by Louis Fisher in 1917. Sheet music was published by Jerome H Remick & Co.
