To solve problems that a reversible circular knitted fabric and clothes utilizing excellent physical properties of polypropylene fibers are demanded.

The reversible circular knitted fabric 1 has a different knitted state between one surface 2 and the other surface 3. The knitted fabric 1 is composed so that the one surface 2 is mainly formed from a polypropylene yarn 5, and a yarn 4 composed of a material different from that of the polypropylene yarn 5 is used as the yarn on the other surface mainly forming the other surface 3. The yarn 4 for the other surface composed of at least one kind selected from the group consisting of cotton, silk, wool and rayon can be used. The clothes can be formed by using the reversible circular knitted fabric 1. In this case, the one surface 2 mainly formed of the polypropylene yarn 5 is used as the surface on the skin side to afford effects such that the clothes are warm and easily dried.
