Ready-made pajamas, of which 11 for summer and 15 for winter use, were examined. 1) The style of trousers differed much. 2) The approximate rate of cloth shrinkage was 8% in width and 6% in length in the case of the summer pajamas. Concerning the winter pajamas, the rate of shrinkage was 7% in width and 12% in length. The 100% cotton ones shrank more than those of mixed fabric. 3) After washing, each fabric showed a higher speed and rate of water absorption. However, two kinds of seersucker cloth and the fabric with 50% polyester blended were slightly inferior in water absorption. 4) Almost all of the winter pajamas and about 60% of the summer ones showed deterioration in texture and colour. Impairment was slight, though one of the pajamas resulted in an open seam at the hem. Ornaments and shirring were apt to be impaired. The foregoing results are important for establishing both proper standards for choosing ready-made pajamas and stimulating the pupils to make good pajamas.
