Inner wear and high-gauge circular knitting machine, and knitting method using the high-gauge circular knitting machine

The invention provides innerwear with a structure in which the body fabric and the hem are joined together without sewing and which has outstanding effects in discrimination as products and in showing individuality for users. The innerwear includes a body fabric 2 made of a cylindrical double material with a body size and a hem 3 disposed at the end of the body fabric 2 and having apparently different texture therefrom, the body fabric 2 and the hem 3 being joined to each other without sewing. The body fabric 2 partly has a heterogeneously knitted part 5 with different functions, appearance, and texture therefrom by differentiating the way of knitting in the consecutive knitting process.
