This study is to identify structural relations among perception of up-cycle fashion products, environment-friendly consciousness, and sustainable life-style. The subjects of the study were female undergraduated students who live in Daegu and Kyungbuk region. Data analysis was done using AMOS 19.0 and SPSS 19.0 for Windows. The results are as follows:

First, up-cycle fashion products had a direct effect on environment-friendly consciousness and sustainable life-style. This means that those who are attracted to up-cycle fashion products get more conscious of environment-friendly awareness to protect the environment, which, in turns, affects their sustaibable life-style to lead a environment-conscious life.

Second, environment-friendly consciousness influenced directly sustainable life-style, which implies that interests in the environment and awareness of protecting it leads to sustainable life-stlye where resource saving, social activity, environment protection are considered critical.

Finally, being aware of up-cycle fashion products affects sustaining an eco-friendly life-style through environment-friendly consciousness in an indirect manner. To think of up-cycle fashion products of being attractive and contributing to the environment protection has influence on increasing concerns and importance on the environment, and then such perception of the environment affects sustainable life-style which aims for resource saving, social activities, and environment protection.

In short, if the up-cycle fashion industry further receives good responses with better-designed products and develops to give a good impression to many people, it is expected that those who encouter such products will realize what they have never thought of regarding the environment and they will get willing to lead sustainable life-style.
