Traditional Duofold two layer fabric cotton/wool/nylon blend. Made by Duofold Inc, Mohawk, N.Y.. Vintage 20th century. These three pieces are marked size 14 - possibly youth sizing as it would not be 14 women's although the top has waist shaping so it is definitely not boys. Listing as women's XS. Fabric has natural give. Hight quality traditional long underwear, base layer. Very warm and comfortable. One of the pants is shorter than the other - suspect they may have been dryer dried . Overall condition very good, no stains. Would also make super cute holiday pajamas. Top is pit to pit 15", length 22". Bottoms waist 22-29"
