Methods for making stretch shirting fabric having fabric weight less than 175 g/mSUP2 /SUPand fabric stretch between 15% to 45% in the weft direction are disclosed. A corespun composite elastomeric yarn is produced either (a) by low draft (2.7x or below) core-spinning of the elastomeric yarn, or (b) by pretreating the corespun composite yarn in steam or heated water at temperatures of at least 110° C. to reduce yarn power before dyeing or weaving. The shirting fabric with such corespun composite elastomeric yarn in the weft meets end-use specifications without heat-setting.
